Abstract
ABSTRACT Combat casualty care can be complicated by transport times exceeding the "golden hour," with intervention and resuscitation limited to what the medic can carry. Pharmaceutical albumin comes highly saturated with non-esterified fatty acids (NEFAs). We recently showed that treatment with 25% bovine serum albumin (BSA) loaded with oleic acid (OA), but not NEFA-free BSA, improved survival for hours after severe hemorrhage and often eliminated the need for resuscitation in rats. However, it was unknown if pharmaceutical albumin, derived from human sources and loaded with caprylic acid (CA), would have the same benefits. We compared adjunct treatment with OA-saturated BSA, CA-saturated BSA, pharmaceutical human serum albumin (HSA), or a no-albumin control in a similar rat hemorrhagic shock model to determine if the three NEFA-albumin groups provided the same benefits relative to control. We found almost no significant differences among the NEFA-albumin groups in any measure. Mortality in controls was too low to allow for detection of improvement in survival, but NEFA-albumin groups had significantly improved hemodynamics, lactate clearance, and greatly reduced fluid requirements compared to controls. Contrary to expectations of "dehydration", 25% albumins shifted little additional fluid into the vasculature. Rather, they restored protein to the auto-transfusion fluid. NEFA-albumin did not worsen lung permeability, but we observed a loss of circulating protein suggesting it may have increased overall vascular permeability. Our findings suggest that, though imperfect, 25% HSA could be a solution for resuscitation in austere conditions requiring prolonged field care.

Abstract
Curcumin is known to have immunomodulatory potential in addition to anti-oxidant, anti-inflammatory and anti-carcinogenic effects. The aim of the present study is to investigate the therapeutic effects of curcumin on immune-mediated renal disease in an anti-glomerular basement membrane (GBM) model (representing acute kidney Injury, AKI) and murine lupus model (representing chronic kidney disease, CKD). In the AKI model, female anti-GBM 129/svj mice were administered with curcumin right before disease induction. In the CKD model, female MRL.lpr mice at the age of 8-10 weeks old were treated with curcumin or placebo via oral gavage daily for two months. After treatment, serum autoantibody levels, splenomegaly and spleen cellularity were reduced in murine lupus. Collectively, curcumin ameliorated kidney disease in the two mouse models with either acute or chronic nephritis, as marked by reduced proteinuria, blood urea nitrogen, glomerulonephritis, crescent formation, tubule-interstitial disease, and renal infiltration by lymphocytes. In addition, curcumin treatment reduced activation of the NFkB, MAPK, AKT and pBAD pathways either systemically, or within the inflamed kidneys. These findings suggest that natural food supplements could become an alternative approach to ameliorating immune-mediated kidney diseases.

Abstract
Recently developed potent and selective CDK4/6 inhibitors fall into two classes based on structure and toxicity profiles in clinical studies. One class, exemplified by palbociclib and ribociclib, exhibits neutropenia as a dose-limiting toxicity and requires discontinuous dosing. In contrast, the structurally distinct CDK4/6 inhibitor abemaciclib is dosed continuously, and has diarrhea and fatigue as dose-limiting toxicities. In preclinical models, palbociclib has been extensively studied and induces cell cycle inhibition in an RB-dependent manner. Thus far, abemaciclib has been less extensively evaluated. We found that abemaciclib cell cycle inhibitory activity is RB-dependent at clinically achievable concentrations. Abemaciclib elicited potent suppression of RB/E2F regulated genes associated with prognosis in ER-positive breast cancer. However, unlike palbociclib, at 250nM-1 µM doses abemaciclib induced cell death in RB-deficient cell lines. This response was associated with a rapidly-induced multi-vacuolar phenotype indicative of lysosomal membrane permeabilization that could be ameliorated with chloroquine. This event was not a reflection of inhibition of other CDK family members, but could be recapitulated with CBX4945 that inhibits casein and DYRK/HIPK kinases. To determine if these "off-target" features of abemaciclib were observed in vivo, mice harboring matched RB-positive and negative xenografts were treated with palbociclib and abemaciclib. In vivo, all of the apparent activity of abemaciclib was RB-dependent and strongly elicited suppression of cell cycle regulatory genes in a fashion markedly similar to palbociclib. Using gene expression data from cell lines and tumors treated with abemaciclib and palbociclib a composite signature of response to CDK4/6 inhibition was developed that included many genes that are individually required for tumor cell proliferation or viability. These data indicate that while abemaciclib and palbociclib can exert distinct biological and molecular effects, there are common gene expression features that could be broadly utilized in measuring the response to CDK4/6 inhibition.

Abstract
Tsai et al. demonstrate that loss of Bim (BCL2L11) in myeloid cells in mice (LysMCreBimfl/fl) is sufficient to induce systemic autoimmunity. Kidney macrophages in LysMCreBimfl/fl mice possess a proinflammatory transcriptional signature and signal through TRIF to cause end-stage glomerulonephritis. The Bcl-2 family is considered the guardian of the mitochondrial apoptotic pathway. We demonstrate that Bim acts as a molecular rheostat by controlling macrophage function not only in lymphoid organs but also in end organs, thereby preventing the break in tolerance. Mice lacking Bim in myeloid cells (LysMCreBimfl/fl) develop a systemic lupus erythematosus (SLE)–like disease that mirrors aged Bim−/− mice, including loss of marginal zone macrophages, splenomegaly, lymphadenopathy, autoantibodies (including anti-DNA IgG), and a type I interferon signature. LysMCreBimfl/fl mice exhibit increased mortality attributed to glomerulonephritis (GN). Moreover, the toll-like receptor signaling adaptor protein TRIF (TIR-domain–containing adapter-inducing interferon-β) is essential for GN, but not systemic autoimmunity in LysMCreBimfl/fl mice. Bim-deleted kidney macrophages exhibit a novel transcriptional lupus signature that is conserved within the gene expression profiles from whole kidney biopsies of patients with SLE. Collectively, these data suggest that the Bim may be a novel therapeutic target in the treatment of SLE.

Abstract
The retinoblastoma tumor suppressor (RB) was the first identified tumor suppressor based on germline predisposition to the pediatric eye tumor. Since these early studies, it has become apparent that the functional inactivation of RB is a common event in nearly all human malignancy. A great deal of research has gone into understanding how the loss of RB promotes tumor etiology and progression. Since malignant tumors are characterized by aberrant cell division, much of this research has focused upon the ability of RB to regulate the cell cycle by repression of proliferation-related genes. However, it is progressively understood that RB is an important mediator of multiple functions. One area that is gaining progressive interest is the emerging role for RB in regulating diverse features of immune function. These findings suggest that RB is more than simply a regulator of cellular proliferation; it is at the crossroads of proliferation and the immune response. Here we review the data related to the functional roles of RB on the immune system, relevance to immune evasion, and potential significance to the response to immune-therapy.

Abstract
Systemic lupus erythematosus (SLE) is characterized by antibody-mediated chronic inflammation in the kidney, lung, skin, and other organs to cause inflammation and damage. Several inflammatory pathways are dysregulated in SLE, and understanding these pathways may improve diagnosis and treatment. In one such pathway, Axl tyrosine kinase receptor responds to Gas6 ligand to block inflammation in leukocytes. A soluble form of the Axl receptor ectodomain (sAxl) is elevated in serum from patients with SLE and lupus-prone mice. We hypothesized that sAxl in SLE serum originates from the surface of leukocytes and that the loss of leukocyte Axl contributes to the disease. We determined that macrophages and B cells are a source of sAxl in SLE and in lupus-prone mice. Shedding of the Axl ectodomain from the leukocytes of lupus-prone mice is mediated by the matrix metalloproteases ADAM10 and TACE (ADAM17). Loss of Axl from lupus-prone macrophages renders them unresponsive to Gas6-induced anti-inflammatory signaling in vitro. This phenotype is rescued by combined ADAM10/TACE inhibition. Mice with Axl-deficient macrophages develop worse disease than controls when challenged with anti-glomerular basement membrane (anti-GBM) sera in an induced model of nephritis. ADAM10 and TACE also mediate human SLE PBMC Axl cleavage. Collectively, these studies indicate that increased metalloprotease-mediated cleavage of leukocyte Axl may contribute to end organ disease in lupus. They further suggest dual ADAM10/TACE inhibition as a potential therapeutic modality in SLE.

Abstract
PURPOSE Pancreatic ductal adenocarcinoma (PDA) is associated with an immunosuppressive microenvironment that supports the growth of the malignancy as well as immune system evasion. Here we examine markers of immunosuppression in PDA within the context of the glycolytic tumor microenvironment, their interrelationship with tumor biology and association with overall survival. EXPERIMENTAL DESIGN We utilized tissue microarrays consisting of 223 PDA patients annotated for clinical stage, tumor size, lymph node involvement, and survival. Expression of CD163, FoxP3, PD-L1, and MCT4 was assessed by IHC and statistical associations were evaluated by univariate and multivariate analysis. Multimarker subtypes were defined by random forest analysis. Mechanistic interactions were evaluated using PDA cell lines and models for myeloid differentiation. RESULTS PDA exhibits discrete expression of CD163, FoxP3, and PD-L1 with modest individual significance. However, combined low expression of these markers was associated with improved prognosis (P = 0.02). PDA tumor cells altered macrophage phenotype and function, which supported enhanced invasiveness in cell-based models. Lactate efflux mediated by MCT4 was associated with, and required for, the selective conversion of myeloid cells. Correspondingly, MCT4 expression correlated with immune markers in PDA cases, and increased the significance of prognostic subtypes (P = 0.002). CONCLUSIONS There exists a complex interplay between PDA tumor cells and the host immune system wherein immunosuppression is associated with negative outcome. MCT4 expression, representative of the glycolytic state of PDA, contributes to the phenotypic conversion of myeloid cells. Thus, metabolic status of PDA tumors is an important determinant of the immunosuppressive environment. Clin Cancer Res; 22(14); 3606-17. ©2016 AACR.

Abstract
INTRODUCTION Although caspase-8 is a well-established initiator of apoptosis and suppressor of necroptosis, recent evidence suggests that this enzyme maintains functions beyond its role in cell death. As cells of the innate immune system, and in particular macrophages, are now at the forefront of autoimmune disease pathogenesis, we examined the potential involvement of caspase-8 within this population. METHODS Cre (LysM) Casp8 (fl/fl) mice were bred via a cross between Casp8 (fl/fl) mice and Cre (LysM) mice, and RIPK3 (-/-) Cre (LysM) Casp8 (fl/fl) mice were generated to assess the contribution of receptor-interacting serine-threonine kinase (RIPK)3. Immunohistochemical and immunofluorescence analyses were used to examine renal damage. Flow cytometric analysis was employed to characterize splenocyte distribution and activation. Cre (LysM) Casp8 (fl/fl) mice were treated with either Toll-like receptor (TLR) agonists or oral antibiotics to assess their response to TLR activation or TLR agonist removal. Luminex-based assays and enzyme-linked immunosorbent assays were used to measure cytokine/chemokine and immunoglobulin levels in serum and cytokine levels in cell culture studies. In vitro cell culture was used to assess macrophage response to cell death stimuli, TLR activation, and M1/M2 polarization. Data were compared using the Mann-Whitney U test. RESULTS Loss of caspase-8 expression in macrophages promotes onset of a mild systemic inflammatory disease, which is preventable by the deletion of RIPK3. In vitro cell culture studies reveal that caspase-8-deficient macrophages are prone to a caspase-independent death in response to death receptor ligation; yet, caspase-8-deficient macrophages are not predisposed to unchecked survival, as analysis of mixed bone marrow chimeric mice demonstrates that caspase-8 deficiency does not confer preferential expansion of myeloid populations. Loss of caspase-8 in macrophages dictates the response to TLR activation, as injection of TLR ligands upregulates expression of costimulatory CD86 on the Ly6C(high)CD11b(+)F4/80(+) splenic cells, and oral antibiotic treatment to remove microbiota prevents splenomegaly and lymphadenopathy in Cre (LysM) Casp8 (fl/fl) mice. Further, caspase-8-deficient macrophages are hyperresponsive to TLR activation and exhibit aberrant M1 macrophage polarization due to RIPK activity. CONCLUSIONS These data demonstrate that caspase-8 functions uniquely in macrophages by controlling the response to TLR activation and macrophage polarization in an RIPK-dependent manner.

Abstract
Systemic lupus erythematosus (SLE) and lupus nephritis (LN) have strong concomitance with cardiovascular disease that cannot be explained fully by typical risk factors. We examined the possibility that serum or urine expression of adipokines may act as biomarkers for LN, as these proteins have been associated previously with cardiovascular disease as well as SLE. Antibody arrays were performed on serum and urine from lupus patients and matched controls using a cross-sectional study design. From the initial array-based screening data of 15 adipokines, adiponectin, leptin and resistin were selected for validation by enzyme-linked immunosorbent assay (ELISA). Correlations were determined between adipokine expression levels and measures of disease activity or lupus nephritis. The expression of adiponectin and resistin was increased in both sera and urine from LN patients, while leptin was increased in LN patient sera, compared to matched controls. Serum resistin, but not urine resistin, was correlated with measures of renal dysfunction in LN. Serum resistin expression may be useful as a marker of renal dysfunction in patients with LN, although longitudinal studies are warranted. Further studies are necessary to determine if resistin has functional consequences in LN.

Abstract
UNLABELLED Cancers mediated by viral etiology must exhibit deregulated cellular proliferation and evade immune recognition. The role of the retinoblastoma tumor suppressor (RB) pathway, which is lost at relatively high frequency in hepatocellular carcinoma (HCC), has recently been expanded to include the regulation of innate immune responsiveness. In this study we investigated the coordinate impact of RB-loss on cell cycle control and immune function in the liver. We found that RB depletion in hepatoma cells resulted in a compromised immunological response to multiple stimuli and reduced the potential of these cells to recruit myeloid cells. Viral-mediated liver-specific RB deletion in vivo led to the induction of genes associated with proliferation and cell cycle entry as well as the significant attenuation of genes associated with immune function, as evidenced by decreases in cytokine and chemokine expression, leukocyte recruitment, and hepatic inflammation. To determine if these changes in gene expression were instructive in human disease, we compared our liver-specific RB-loss gene signature to existing profiles of HCC and found that this signature was associated with disease progression and confers a worse prognosis. CONCLUSION Our data confirm that RB participates in the regulation of innate immunity in liver parenchymal cells both in vitro and in vivo and to our knowledge describes the first gene signature associated with HCC that includes both immunoregulatory and proliferative genes and that can also be attributed to the alteration of a single gene in vitro.

Abstract
Caspase-8, an executioner enzyme in the death receptor pathway, was shown to initiate apoptosis and suppress necroptosis. In this study, we identify a novel, cell death-independent role for caspase-8 in dendritic cells (DCs): DC-specific expression of caspase-8 prevents the onset of systemic autoimmunity. Failure to express caspase-8 has no effect on the lifespan of DCs but instead leads to an enhanced intrinsic activation and, subsequently, more mature and autoreactive lymphocytes. Uncontrolled TLR activation in a RIPK1-dependent manner is responsible for the enhanced functionality of caspase-8-deficient DCs, because deletion of the TLR-signaling mediator, MyD88, ameliorates systemic autoimmunity induced by caspase-8 deficiency. Taken together, these data demonstrate that caspase-8 functions in a cell type-specific manner and acts uniquely in DCs to maintain tolerance.

Abstract
Diverse etiologic events are associated with the development of hepatocellular carcinoma. During hepatocarcinogenesis, genetic events likely occur that subsequently cooperate with long-term exposures to further drive the progression of hepatocellular carcinoma. In this study, the frequent loss of the retinoblastoma (RB) tumor suppressor in hepatocellular carcinoma was modeled in response to diverse hepatic stresses. Loss of RB did not significantly affect the response to a steatotic stress as driven by a methionine- and choline-deficient diet. In addition, RB status did not significantly influence the response to peroxisome proliferators that can drive hepatomegaly and tumor development in rodents. However, RB loss exhibited a highly significant effect on the response to the xenobiotic1,4-Bis-[2-(3,5-dichloropyridyloxy)] benzene. Loss of RB yielded a unique proliferative response to this agent, which was distinct from both regenerative stresses and genotoxic carcinogens. Long-term exposure to 1,4-Bis-[2-(3,5-dichloropyridyloxy)] benzene yielded profound tumor development in RB-deficient livers that was principally absent in RB-sufficient tissue. These data demonstrate the context specificity of RB and the key role RB plays in the suppression of hepatocellular carcinoma driven by xenobiotic stress.

Abstract
OBJECTIVE The death receptor Fas is a critical mediator of the extrinsic apoptotic pathway, and its role in mediating lymphoproliferation has been extensively examined. The present study was undertaken to investigate the impact of myeloid cell-specific loss of Fas. METHODS Mice with Fas flanked by loxP sites (Fas(flox/flox) ) were crossed with mice expressing Cre under control of the murine lysozyme M gene promoter (Cre(LysM) ), which functions in mature lysozyme-expressing cells of the myelomonocytic lineage. The genotype for Cre(LysM) Fas(flox/flox) mice was verified by polymerase chain reaction and flow cytometric analysis. Flow cytometric analysis was also used to characterize myeloid, dendritic, and lymphoid cell distribution and activation in bone marrow, blood, and spleen. Luminex-based assays and enzyme-linked immunosorbent assays were used to measure serum cytokine/chemokine and immunoglobulin levels. Renal damage or dysfunction was examined by immunohistochemical and immunofluorescence analysis. RESULTS Cre(LysM) Fas(flox/flox) mice exhibited a systemic lupus erythematosus (SLE)-like disease that included leukocytosis, splenomegaly, hypergammaglobulinemia, antinuclear autoantibody and proinflammatory cytokine production, and glomerulonephritis. Loss of Fas in myeloid cells increased levels of both Gr-1(low) and Gr-1(intermediate) blood monocytes and splenic macrophages and, in a paracrine manner, incited activation of conventional dendritic cells and lymphocytes in Cre(LysM) Fas(flox/flox) mice. CONCLUSION Taken together, these results suggest that loss of Fas in myeloid cells is sufficient to induce inflammatory phenotypes in mice, reminiscent of an SLE-like disease. Thus, Fas in myeloid cells may be considered a suppressor of systemic autoimmunity.

Abstract
Systemic lupus erythematosus (SLE) is a polygenic autoimmune disease characterized by the production of anti-nuclear autoantibodies that lead to subsequent end organ damage. Previous array-based studies in patients with SLE have shown that high immunoglobulin (Ig)G anti-nuclear autoantibody reactivity was associated with severe renal lupus, whereas IgM polyreactivity was associated with less severe disease. To ascertain how different murine lupus strains recapitulate these different autoantibody profiles seen in patients, serum from New Zealand black (NZB)/NZ white (W) F(1), Murphy Roths large (MRL)/lpr, NZ mixed (M)2410 and BXSB strains were compared using a comprehensive array-based screen. The array results were verified using enzyme-linked immunosorbent assays (ELISAs). Serum from MRL/lpr mice exhibited high levels of IgG anti-nuclear antibodies as well as anti-glomerular antibodies and variable levels of antibodies to myosin, Matrigel and thyroglobulin. Elevated anti-nuclear IgG antibodies were associated with severe nephritis in this strain. In contrast, NZM2410 mice exhibited lower IgG autoantibody levels with less severe nephritis but a significantly higher polyreactive IgM autoantibody profile. ELISA analysis confirmed these results. The NZB/NZW F(1) and BXSB strains exhibited an intermediate serological profile. Hence, just as in patients with SLE, whereas strong IgG reactivity to nuclear antigens is associated with severe renal disease, a polyreactive IgM seroprofile is also less ominous in murine lupus.

Abstract
Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that is characterized by a defect in immune tolerance and exacerbated by both the innate and adaptive arms of the immune response. SLE-associated immune hyperactivity can be detected systemically as elevations in levels of cytokines along with their upregulated receptors expressed by hematopoietic cells. Importantly, increased levels of cytokines and their receptors can be observed in target organs, and it is clear that they have important roles in disease pathogenesis. Recent therapeutic strategies have focused on proximal cytokines, such as interferon-α, interleukin (IL)-1, IL-6, and tumor necrosis factor as a result of the efficacious use of biologic agents for intervention in rheumatoid arthritis and other autoimmune diseases. Despite the recent advances in understanding the cytokine networks involved in autoimmune diseases and more specifically in SLE, the diagnosis and prognosis of lupus remain a challenge. Lupus is heterogeneous and unpredictable; moreover, the frequency and severity of flares can be difficult to determine and treat. A better understanding of the regulation of expression of key cytokines and their receptors can likely provide important clues to the pathogenic mechanisms underlying specific forms of SLE, and pave the way toward more effective therapeutics.

Abstract
OBJECTIVE Rheumatoid arthritis (RA) is a destructive autoimmune disease characterized by an increased inflammation in the joint. Therapies that activate the apoptotic cascade may have potential for use in RA; however, few therapeutic agents fit this category. The purpose of this study was to examine the potential of Bim, an agent that mimics the action of Bcl-2 homology 3 (BH3) domain-only proteins that have shown success in preclinical studies of cancer, in the treatment of autoimmune disease. METHODS Synovial tissues from RA and osteoarthritis patients were analyzed for the expression of Bim and CD68 using immunohistochemistry. Macrophages from Bim(-/-) mice were examined for their response to lipopolysaccharide (LPS) using flow cytometry, real-time polymerase chain reaction analysis, enzyme-linked immunosorbent assay, and immunoblotting. Bim(-/-) mice were stimulated with thioglycollate or LPS and examined for macrophage activation and cytokine production. Experimental arthritis was induced using the K/BxN serum-transfer model. A mimetic peptide corresponding to the BH3 domain of Bim (TAT-BH3) was administered as a prophylactic agent and as a therapeutic agent. Edema of the ankles and histopathologic analysis of ankle tissue sections were used to determine the severity of arthritis, its cellular composition, and the degree of apoptosis. RESULTS The expression of Bim was reduced in RA synovial tissue as compared with controls, particularly in macrophages. Bim(-/-) macrophages displayed elevated expression of markers of inflammation and secreted more interleukin-1beta following stimulation with LPS or thioglycollate. TAT-BH3 ameliorated arthritis development, reduced the number of myeloid cells in the joint, and enhanced apoptosis without inducing cytotoxicity. CONCLUSION These data demonstrate that BH3 mimetic therapy may have significant potential for the treatment of RA.

Abstract
Rheumatoid arthritis (RA) is a debilitating disease, resulting in the destruction of bone and cartilage, and in the permanent disfigurement of joints. Although the precise cause of RA is currently unresolved, it has become clear that the damaging effects are a result of the toxic milieu caused by an influx of inflammatory cells and the resulting heightened proinflammatory state within the joint. As the amount of literature suggesting that this preponderance of cells is a result of decreased local apoptosis in the joint continues to increase, in this review, we describe how Bcl-2 family pro-apoptotic BH3-only proteins, particularly Bim and Bid, could act to protect against the development of the disease. We also suggest a role for BH3-mimetic drugs as potential therapeutics in the treatment of RA.

Abstract
Significant morbidity and mortality can be attributed to inflammatory diseases; therefore, a greater understanding of the mechanisms involved in the progression of inflammation is crucial. Here, we demonstrate that p21((WAF1/CIP1)), an established suppressor of cell cycle progression, is a inhibitor of IL-1beta synthesis in macrophages. Mice deficient in p21 (p21(-/-)) display increased susceptibility to endotoxic shock, which is associated with increased serum levels of IL-1beta. Administration of IL-1 receptor antagonist reduces LPS-induced lethality in p21(-/-) mice. Analysis of isolated macrophages, which are one of the central producers of IL-1beta, reveals that deficiency for p21 led to more IL-1beta mRNA and pro-protein synthesis following TLR ligation. The increase in IL-1beta pro-protein is associated with elevated secretion of active IL-1beta by p21(-/-) macrophages. siRNA-mediated knockdown of p21 in human macrophages results in increased IL-1beta secretion as well. A peptide mapping strategy shows that the cyclin-dependent-kinase (CDK)-binding domain of p21 is sufficient to reduce the secretion of IL-1beta by p21(-/-) macrophages. These data suggest a novel role for p21 and specifically for the CDK-binding domain of p21((WAF1/CIP1)) in inhibiting inflammation.

Abstract
Rheumatoid arthritis is an autoimmune disease characterized by hyperplasia of the synovial lining and destruction of cartilage and bone. Recent studies have suggested that a lack of apoptosis contributes to the hyperplasia of the synovial lining and to the failure in eliminating autoreactive cells. Mice lacking Fas or Bim, two pro-apoptotic proteins that mediate the extrinsic and intrinsic death cascades, respectively, develop enhanced K/BxN serum transfer-induced arthritis. Since the pro-apoptotic protein Bid functions as an intermediate between the extrinsic and intrinsic apoptotic pathways, we examined the role that it plays in inflammatory arthritis. Mice deficient in Bid (Bid-/-) show a delay in the resolution of K/BxN serum transfer-induced arthritis. Bid-/- mice display increased inflammation, bone destruction, and pannus formation compared to wild-type mice. Furthermore, Bid-/- mice have elevated levels of CXC chemokine and IL-1β in serum, which are associated with more inflammatory cells throughout the arthritic joint. In addition, there are fewer apoptotic cells in the synovium of Bid-/- compared to Wt mice. These data suggest that extrinsic and intrinsic apoptotic pathways cooperate through Bid to limit development of inflammatory arthritis.

Abstract
The process of thymopoiesis is tightly regulated by a series of selection events which ensure that only functional T-lymphocytes directed against foreign antigens are exported into the periphery. The adaptive immune response largely depends on the regulation of thymocyte development, and thymocytes which fail selection in the thymus are removed by apoptosis. However, the roles of specific apoptotic proteins in early T-lymphocyte development are poorly understood. Here, we report a novel function for Bim in thymocyte development. There is an accumulation of thymocytes in Bim(-/-) mice that lack expression of CD4, CD8, CD44, and CD25 but express CD3 and TCRbeta. Further, the CD4(-)CD8(-)CD25(-)CD44(-)CD3(+)TCRbeta(+) thymocytes are smaller and do not proliferate. These data suggest that these thymocytes are mature DN thymocytes that may have down-regulated the expression of CD4 and CD8. The DN thymocyte phenotype in Bim(-/-) mice is unaffected by the additional loss of Bak or Bax and is similar to the thymic phenotype in mice lacking both Bak and Bax. These data demonstrate that Bim functions to ensure the proper homeostasis of mature thymocytes during selection and thymic export.

Abstract
OBJECTIVE : Rheumatoid arthritis (RA) is characterized by hyperplasia of the synovial lining, inflammation, and destruction of cartilage and bone. Since there are only a few detectable cells undergoing apoptosis in the joint, it is possible that a defect in apoptosis may contribute to synovial hyperplasia. This study sought to identify and characterize the direct role of apoptotic regulators in a mouse model of inflammatory arthritis. METHODS Using a serum transfer model, experimental arthritis was induced in mice lacking the proapoptotic Bcl-2 family genes Bak (Bak-/-), Bax (Bax-/-), or Bim (Bim-/-), as compared with wild-type (WT) control mice. Physical examination for edema of the ankles and histopathologic analysis of ankle sections were used to determine the severity of arthritis. The serum and ankles were examined for production of chemokines and cytokines using enzyme-linked immunosorbent or Luminex-based assays. RESULTS Bim-/- mice displayed increased severity and prolongation of arthritis. In contrast, Bak-/- and Bax-/- mice showed no difference in the severity of arthritis as compared with WT mice. In addition, Bim-/- mice had elevated levels of proinflammatory chemokines and cytokines, decreased joint and serum production of antiinflammatory cytokines, fewer TUNEL-positive cells, and reduced levels of active caspase 3 as compared with WT mice. CONCLUSION These studies are the first to demonstrate a role for the proapoptotic Bcl-2 protein Bim in the effector phase of RA. The findings indicate that Bim potentially functions to repress the effector phase of arthritis by regulating the milieu of the joint and serum, and by inducing apoptosis.

Abstract
One of the central functions of cyclin-dependent kinase inhibitors, such as p21, p27, or p16, is to prevent entry into the cell cycle. However, the question remains as to whether they have other functions in the cell. We previously demonstrated that overexpression of p21 in fibroblasts isolated from patients with rheumatoid arthritis decreases the production of pro-inflammatory molecules. Overexpression of p21 has been also shown to reduce the development of experimental arthritis in mice and rats. To explore the role of endogenous p21 in the development of arthritis, we induced arthritis in p21(-/-) mice using the K/BxN serum transfer model of arthritis. Mice deficient in p21 were more resistant to serum transfer-induced arthritis (K/BxN) than wild-type (wt) control mice. Fewer macrophages were detected in p21(-/-) as compared to wt joints following transfer of K/BxN serum. Chemotaxis assays of bone marrow-derived macrophages from p21(-/-) and wt mice revealed no difference in migration. However, there was a substantial decrease in inflammatory monocytes circulating in peripheral blood and in monocyte precursors in bone marrow of p21(-/-) mice as compared to wt mice. Adoptive transfer of wt bone marrow-derived macrophages into p21(-/-) mice restored the sensitivity to serum transfer-induced arthritis. These data suggest a novel role for p21 in regulating the development and/or differentiation of monocytic populations that are crucial for the induction of inflammatory arthritis.

Abstract
The proapoptotic members of the Bcl-2 family can be subdivided into members that contain several Bcl-2 homology (BH) domains and those that contain only the BH3 domain. Although it is known that BH3-only proteins and the multi-BH domain proteins, Bak and Bax, are essential for programmed cell death, the overlapping role of these two subgroups has not been examined in vivo. To investigate this, we generated Bak/Bim and Bax/Bim double deficient mice. We found that although Bax−/−Bim−/−, but not Bak−/−Bim−/−, mice display webbed hind and front paws and malocclusion of the incisors, both groups of mice present with dysregulated hematopoiesis. Combined loss of Bak and Bim or Bax and Bim causes defects in myeloid and B-lymphoid development that are more severe than those found in the single knock-out mice. Bak−/−Bim−/− mice have a complement of thymocytes that resembles those in control mice, whereas Bax−/−Bim−/− mice are more similar to Bim−/− mice. However, thymocytes isolated from Bak−/−Bim−/− or Bax−/−Bim−/− mice are markedly more resistant to apoptotic stimuli mediated by the intrinsic pathway as compared with thymocytes from single-knockout mice. These data suggest an essential overlapping role for Bak or Bax and Bim in the intrinsic apoptotic pathway.

Abstract
Over 1 billion monocytes are produced daily, with a small percentage differentiating into macrophages, suggesting that excess monocytes are deleted through a tightly regulated process. Although the in vivo mechanism governing monocyte/macrophage homeostasis is unknown, deletion of monocytes in culture is mediated by the Fas death pathway and is blocked by M-CSF. To determine the in vivo significance of Fas in monocyte development, mice lacking Fas (lpr/lpr) and mice deficient in Fas and M-CSF were examined. Compared with congenic control C57BL/6 (B6) mice, lpr/lpr mice displayed increased numbers of circulating monocytes. The lack of Fas in M-CSF-deficient mice resulted in an enhanced percentage, but not total numbers, of monocytes. Fas deficiency led to an increase in myeloid bone marrow progenitor potential only in M-CSF-intact mice. Although lpr/lpr and B6 mice had similar numbers of tissue macrophages, the loss of Fas in M-CSF-deficient mice was sufficient to increase the number of macrophages in a subset of tissues. Additionally, after stimulation with thioglycolate, lpr/lpr and B6 mice showed equivalent numbers of peritoneal macrophages. However, Fas-deficient peritoneal macrophages displayed a marked increase in spontaneous and LPS-induced proinflammatory molecule production. Moreover, Fas-deficient mice showed enhanced systemic inflammatory arthritis associated with up-regulation of IL-1beta and CCL2 secretion, elevated numbers of inflammatory monocytes, and increased numbers of tissue macrophages. Collectively, these data suggest that Fas may be required for maintaining circulating monocytes and for suppressing macrophage activation and recruitment that are stimulus dependent.

Abstract
OBJECTIVE Fas ligand (FasL) can induce apoptosis in cells bearing the Fas receptor. The role of FasL in the vasculature with regard to atherosclerosis is controversial. This study examined the function of endothelial FasL during atherosclerosis. METHODS AND RESULTS Transgenic (Tg) mice that specifically overexpress different levels of FasL on vascular endothelial cells were crossed into the apolipoprotein E-knockout background (ApoE-KO) to generate ApoE-KO/FasL-Tg mice. Although plasma cholesterol and triglyceride levels were not different between ApoE-KO/FasL-Tg mice and ApoE-KO mice after 12 weeks of a high-fat diet, overexpression of the FasL transgene significantly reduced atherosclerotic lesion area in aortae by 49%. The reduction of atherosclerotic lesion area was more pronounced in thoracic and abdominal aortae than in the aortic arch, and a 34% reduction in lesion area was observed in aortic root sections from the ApoE-KO/FasL-Tg group compared with the ApoE-KO group. Immunostaining revealed significant decreases in both macrophage and CD8 T-cell accumulation in lesions of ApoE-KO/FasL-Tg mice. ApoE-KO/FasL-Tg mice that express lower levels of endothelial FasL also displayed reduced lesion size, but this reduction was statistically significant at the aortic arch only. CONCLUSIONS Overexpression of endothelial FasL is antiinflammatory and inhibits atherosclerosis under hypercholesterolemic conditions.

Abstract
Thermal shrinkage of collagen currently is being used in orthopaedic surgery to treat ligamentous laxity. Understanding the kinetics of collagen shrinkage is key to revealing the events that take place during application of thermal energy. To elucidate the thermokinetic properties of collagen, punch biopsies of bovine joint capsule were immersed in a heated saline bath at temperatures between 20 degrees and 90 degrees C for periods up to 60 minutes. The resulting tissue thermal shrinkage was measured by the change in the cross-sectional area of the specimens. Only a small amount of shrinkage occurred at temperatures below 63 degrees C, and increasing amounts and rates of shrinkage were seen at temperatures between 63 degrees and 72 degrees C. The denaturation kinetics of bovine knee collagen, which could be described by a first order reaction rate, had an activation energy of 2.3 x 10(5) kJ/mol.

Abstract
Perineural spread (PNS) is a poor prognostic factor associated with increased risk of local recurrence and nodal metastasis and reduced survival of patients with squamous cell carcinoma of the head and neck (SCCHN). There is some evidence to indicate that neural cell adhesion molecules (NCAMs) may play a role in PNS of a variety of tumor types. We performed this study to investigate whether NCAM expression can be used as a predictor of PNS in SCCHN. The surgical specimens of 66 patients with SCCHN were evaluated with monoclonal IgG antibody immunoperoxidase staining for NCAM. Of the 41 specimens with PNS, 38 (93%) showed evidence of NCAM expression. In contrast, only 9 specimens (36%) without PNS expressed NCAMs. The difference in NCAM expression between the study and control groups was statistically significant (P < 0.01).

Abstract
PURPOSE Amiodarone is an antiarrythmic agent, which is often successfully used when all other antiarrythmics have failed. Sterile epididymitis is a recognized complication of treatment in adults, occurring in up to 11% of patients. To date there have been no reported cases of amiodarone induced epididymitis in children. We present a previously unrecognized cause of epididymitis in boys. MATERIALS AND METHODS The medical records, including radiographic imaging, pathology and operative reports, of 2 postpubertal boys who had sterile epididymitis after prolonged therapy with amiodarone were reviewed. RESULTS In both cases the onset of scrotal pain and subsequent evaluation led to diagnosis of epidydimitis. Amiodarone was determined to be the cause, and cessation of the drug resulted in symptom resolution in 1 case. CONCLUSIONS While it remains uncertain, the pathophysiology of amiodarone induced epididymitis is likely related to its high concentration in testicular tissue. Recognition that amiodarone is a rare but significant cause of epididymitis in children is important to prevent unnecessary surgery in high risk patients. Amiodarone induced epididymitis in children tends to be a self-limited process and of secondary importance to the serious cardiac disease. Whereas discontinuing amiodarone risks sudden cardiac death, a reduction in dosage or temporary cessation of the drug may result in rapid resolution of the epididymitis.

Abstract
OBJECTIVE To evaluate the efficacy of a home-based intervention on the growth and development of children with nonorganic failure to thrive (NOFTT). DESIGN Randomized clinical trial. PARTICIPANTS The NOFTT sample included 130 children (mean age, 12.7 months; SD, 6.4) recruited from urban pediatric primary care clinics serving low income families. All children were younger than 25 months with weight for age below the fifth percentile. Eligibility criteria included gestational age of at least 36 weeks, birth weight appropriate for gestational age, and no significant history of perinatal complications, congenital disorders, chronic illnesses, or developmental disabilities. Children were randomized into two groups: clinic plus home intervention (HI) (n = 64) or clinic only (n = 66). There were no group differences in children's age, gender, race, or growth parameters, or on any of the family background variables. Most children were raised by single, African-American mothers who received public assistance. Eighty-nine percent of the families (116 of 130) completed the 1-year evaluation. INTERVENTIONS All children received services in a multidisciplinary growth and nutrition clinic. A community-based agency provided the home intervention. Families in the HI group were scheduled to receive weekly home visits for 1 year by lay home visitors, supervised by a community health nurse. The intervention provided maternal support and promoted parenting, child development, use of informal and formal resources, and parent advocacy. MEASUREMENTS Growth was measured by standard procedures and converted to z scores for weight for height and height for age to assess wasting and stunting. Cognitive and motor development were measured with the Bayley Scales of Infant Development, and language development was measured by the Receptive/Expressive Emergent Language Scale. Both scales were administered at recruitment and at the 12-month follow-up. Parent-child interaction was measured by observing mothers and children during feeding at recruitment and at the 12-month follow-up, and the quality of the home was measured by the Home Observation Measure of the Environment 18 months after recruitment. ANALYSES Repeated-measures multivariate analyses of covariance were used to examine changes in children's growth and development and parent-child interaction. Analyses of covariance were used to examine the quality of the home. Independent variables were intervention status and age at recruitment (1.0 to 12.0 vs 12.1 to 24.9 months). Maternal education was a covariate in all analyses. When changes in developmental status and parent-child interaction were examined, weight for height and height for age at recruitment were included as covariates. RESULTS Children's weight for age, weight for height, and height for age improved significantly during the 12-month study period, regardless of intervention status. Children in the HI group had better receptive language over time and more child-oriented home environments than children in the clinic-only group. The impact of intervention status on cognitive development varied as a function of children's ages at recruitment, with younger children showing beneficial effects of home intervention. There were no changes in motor development associated with intervention status. During the study period, children gained skills in interactive competence during feeding, and their parents became more controlling during feeding, but differences were not associated with intervention status. CONCLUSIONS Findings support a cautious optimism regarding home intervention during the first year of life provided by trained lay home visitors. Early home intervention can promote a nurturant home environment effectively and can reduce the developmental delays often experienced by low income, urban infants with NOFTT: Subsequent investigations of home intervention should consider alternative options for toddlers with NOFTT:

Abstract
The endogenous auditory P300 event-related potential (P3) has been used to differentiate functional and organic cognitive disorders in adults. We found that children with organic cognitive impairments (as determined by the Halstead-Reitan [HR] test) had greater P3 latencies than children with normal HR evaluations. The P3 and HR showed 85% agreement in independent assessments of functional or organically based cognitive impairment in children. Mini-Mental-State, IQ, EEG evaluations, and clinical suspicions of "organicity" with respect to cognitive function were similarly associated with P3 latency.

Abstract
An elderly woman had dyspnea, a thyroid mass and multiple lung nodules on chest radiographs. She developed hypereosinophilia over a three-month period in which multiple diagnostic procedures were performed, without definition of the disease process. At post-mortem examination, the primary lesion was found to be a poorly differentiated carcinoma of the thyroid, metastatic to lung. This is the second case of hypereosinophilia related to metastatic thyroid carcinoma. The intensity of the hypereosinophilia in this case was increased by the administration of thyroid-stimulating hormone and by the development of necrosis of the lung nodules.
