Abstract
Introduction Increasing evidence has shown that coronavirus disease 19 (COVID-19) severity is driven by a dysregulated immunological response. Previous studies have demonstrated that natural killer (NK) cell dysfunction underpins severe illness in COVID-19 patients, but have lacked an in-depth analysis of NK cell markers as a driver of death in the most critically ill patients. Methods We enrolled 50 non-vaccinated hospitalized patients infected with the initial virus or the alpha variant of SARS-CoV-2 with moderate or severe illness, to evaluate phenotypic and functional features of NK cells. Results Here, we show that, consistent with previous studies, evolution NK cells from COVID-19 patients are more activated, with the decreased activation of natural cytotoxicity receptors and impaired cytotoxicity and IFN-γ production, in association with disease regardless of the SARS-CoV-2 strain. Fatality was observed in 6 of 17 patients with severe disease; NK cells from all of these patients displayed a peculiar phenotype of an activated memory-like phenotype associated with massive TNF-α production. Discussion These data suggest that fatal COVID-19 infection is driven by an uncoordinated inflammatory response in part mediated by a specific subset of activated NK cells.

Abstract
The COVID-19 pandemic has occurred due to infection caused by the SARS-CoV-2 coronavirus, which impacts gestation and pregnancy. In SARS-CoV-2 infection, only very rare cases of vertical transmission have been reported, suggesting that fetal immune imprinting due to a maternal infection is probably a result of changes in maternal immunity. Natural killer (NK) cells are the leading maternal immune cells that act as a natural defense system to fight infections. They also play a pivotal role in the establishment and maintenance of pregnancy. While peripheral NK cells display specific features in patients infected with SARS-CoV-2 in the general population, information remains elusive in pregnant mothers and neonates. In the present study, we analyzed the characteristics of NK cells isolated from both neonatal umbilical cord blood and maternal peripheral blood close to the time of delivery. Phenotype and functions were compared in 18 healthy pregnant women and 34 COVID-19 patients during pregnancy within an ongoing infection (PCR+; N = 15) or after recovery (IgG+PCR−; N = 19). The frequency of NK cells from infected women and their neonates was correlated with the production of inflammatory cytokines in the serum. The expression of NKG2A and NKp30, as well as degranulation of NK cells in pregnant women with ongoing infection, were both negatively correlated to estradiol level. Furthermore, NK cells from the neonates born to infected women were significantly decreased and also correlated to estradiol level. This study highlights the relationship between NK cells, inflammation, and estradiol in patients with ongoing infection, providing new insights into the impact of maternal SARS-CoV-2 infection on the neonate.

Abstract
Abstract
Background
Left atrial appendage (LAA) electrical isolation (ei) may be achieved via radiofrequency (RF) energy applications at the level of the appendage ostium targeting the sites of earliest activation recorded by a mapping catheter. Notably, RF has long been used in vascular, orthopedic, and aesthetic surgery to promote thermal–induced collagen matrix contraction, fibrosis, and tissue retraction. LAA anatomical changes associated to RF–induced tissue retraction have never been reported.
Objective
To quantify the anatomical changes of the LAA ostium following RF–based LAAei.
Methods
Thirty–four consecutive patients requiring AF ablation with LAAei underwent transesophageal echocardiography (TEE) within 7 days before (baseline TEE) and >6 months after (follow–up TEE) ablation. The diameter of LAA orifice and landing zone were measured at 4 different views (0°, 45°, 90°, 135°). Measurements were performed by two independent reviewers blinded to the patient’s identity.
Results
Among 34 AF patients (68±7yrs, 73.5% males), the LAA morphology was classified as chicken wing in 15 (44%) patients, windsock in 10 (29%), cactus in 6 (18%), and cauliflower in 3 (9%). At baseline TEE, the mean maximum and mean minimum ostial diameters were 25±4mm and 22±4mm, respectively. The mean maximum and mean minimum diameters of the landing zone were 26±4mm and 23±3mm, respectively. On average, LAAei was achieved after 16±7 minutes of RF at a power of 45–47W. Follow–up TEE was performed 257±148 days after LAAei. The median LAA contraction velocity was 0.1 m/s (IQR: 0.04–0.18) and was significantly impaired in all patients. At follow–up TEE, the mean maximum and mean minimum ostial diameters were 19±4mm and 17±3mm, respectively. The mean maximum and mean minimum diameters of the landing zone were 20±4mm and 18±4mm, respectively. The mean relative reduction of the ostium and the landing zone were –24.4% and –22.5%, respectively. Box–Whisker plots of the maximum and minimum ostial diameters before and after LAAei are reported in Fig. 1.
Conclusion
RF led to a > 20% reduction of the diameters of the ostium and the landing zone. These changes may have important implications for a successful percutaneous occlusion procedure and justify a staged approach of isolation and occlusion.

Abstract
Zika virus (ZIKV) is a mosquito-borne flavivirus that has emerged as a global concern because of its impact on human health. ZIKV infection during pregnancy can cause microcephaly and other severe brain defects in the developing fetus and there have been reports of the occurrence of Guillain-Barré syndrome in areas affected by ZIKV. NK cells are activated during acute viral infections and their activity contributes to a first line of defense because of their ability to rapidly recognize and kill virus-infected cells. To provide insight into NK cell function during ZIKV infection, we have profiled, using mass cytometry, the NK cell receptor-ligand repertoire in a cohort of acute ZIKV-infected female patients. Freshly isolated NK cells from these patients contained distinct, activated, and terminally differentiated, subsets expressing higher levels of CD57, NKG2C, and KIR3DL1 as compared with those from healthy donors. Moreover, KIR3DL1+ NK cells from these patients produced high levels of IFN-γ and TNF-α, in the absence of direct cytotoxicity, in response to in vitro stimulation with autologous, ZIKV-infected, monocyte-derived dendritic cells. In ZIKV-infected patients, overproduction of IFN-γ correlated with STAT-5 activation (r = 0.6643; p = 0.0085) and was mediated following the recognition of MHC class 1-related chain A and chain B molecules expressed by ZIKV-infected monocyte-derived dendritic cells, in synergy with IL-12 production by the latter cells. Together, these findings suggest that NK cells contribute to the generation of an efficacious adaptive anti-ZIKV immune response that could potentially affect the outcome of the disease and/or the development of persistent symptoms.

Abstract
EBV-positive and EBV-negative posttransplant lymphoproliferative disorders (PTLDs) arise in different immunovirological contexts and might have distinct pathophysiologies. To examine this hypothesis, we conducted a multicentric prospective study with 56 EBV-positive and 39 EBV-negative PTLD patients of the K-VIROGREF cohort, recruited at PTLD diagnosis and before treatment (2013-2019), and compared them to PTLD-free Transplant Controls (TC, n = 21). We measured absolute lymphocyte counts (n = 108), analyzed NK- and T cell phenotypes (n = 49 and 94), and performed EBV-specific functional assays (n = 16 and 42) by multiparameter flow cytometry and ELISpot-IFNγ assays (n = 50). EBV-negative PTLD patients, NK cells overexpressed Tim-3; the 2-year progression-free survival (PFS) was poorer in patients with a CD4 lymphopenia (CD4+ <300 cells/mm3 , p < .001). EBV-positive PTLD patients presented a profound NK-cell lymphopenia (median = 60 cells/mm3 ) and a high proportion of NK cells expressing PD-1 (vs. TC, p = .029) and apoptosis markers (vs. TC, p < .001). EBV-specific T cells of EBV-positive PTLD patients circulated in low proportions, showed immune exhaustion (p = .013 vs. TC) and poorly recognized the N-terminal portion of EBNA-3A viral protein. Altogether, this broad comparison of EBV-positive and EBV-negative PTLDs highlight distinct patterns of immunopathological mechanisms between these two diseases and provide new clues for immunotherapeutic strategies and PTLD prognosis.

Abstract
Systemic lupus erythematosus (SLE) is a severe autoimmune disease of unknown etiology. The major histocompatibility complex (MHC) class I-related chain A (MICA) and B (MICB) are stress-inducible cell surface molecules. MICA and MICB label malfunctioning cells for their recognition by cytotoxic lymphocytes such as natural killer (NK) cells. Alterations in this recognition have been found in SLE. MICA/MICB can be shed from the cell surface, subsequently acting either as a soluble decoy receptor (sMICA/sMICB) or in CD4+ T-cell expansion. Conversely, NK cells are frequently defective in SLE and lower NK cell numbers have been reported in patients with active SLE. However, these cells are also thought to exert regulatory functions and to prevent autoimmunity. We therefore investigated whether, and how, plasma membrane and soluble MICA/B are modulated in SLE and whether they influence NK cell activity, in order to better understand how MICA/B may participate in disease development. We report significantly elevated concentrations of circulating sMICA/B in SLE patients compared with healthy individuals or a control patient group. In SLE patients, sMICA concentrations were significantly higher in patients positive for anti-SSB and anti-RNP autoantibodies. In order to study the mechanism and the potential source of sMICA, we analyzed circulating sMICA concentration in Behcet patients before and after interferon (IFN)-α therapy: no modulation was observed, suggesting that IFN-α is not intrinsically crucial for sMICA release in vivo. We also show that monocytes and neutrophils stimulated in vitro with cytokines or extracellular chromatin up-regulate plasma membrane MICA expression, without releasing sMICA. Importantly, in peripheral blood mononuclear cells from healthy individuals stimulated in vitro by cell-free chromatin, NK cells up-regulate CD69 and CD107 in a monocyte-dependent manner and at least partly via MICA-NKG2D interaction, whereas NK cells were exhausted in SLE patients. In conclusion, sMICA concentrations are elevated in SLE patients, whereas plasma membrane MICA is up-regulated in response to some lupus stimuli and triggers NK cell activation. Those results suggest the requirement for a tight control in vivo and highlight the complex role of the MICA/sMICA system in SLE.

Abstract
Dengue virus (DENV) is the most widespread arbovirus worldwide and is responsible for major outbreaks. The host's immune response plays a crucial role in controlling this infection but might also contribute to the promotion of viral spread and immunopathology. In response to DENV infection, NK cells preferentially produce cytokines and are cytotoxic in the presence of specific antibodies. Here, we identified that DENV-2 inhibits glycogen synthase kinase 3 (GSK-3) activity to subsequently induce MHC class-1-related chain (MIC) A and MIC-B expression and IL-12 production in monocyte-derived DCs, independently of the STAT-3 pathway. The inhibition of GSK-3 by DENV-2 or small molecules induced MIC-A/B expression on monocyte-derived DCs, resulting in autologous NK cells of a specific increase in IFN-γ and TNF-α production, in the absence of direct cytotoxicity. Together, these findings identified GSK-3 as a regulator of MIC-A/B expression and suggested its role in DENV-2 infection to specifically induce cytokine production by NK cells.

Abstract
Background Autism spectrum disorders (ASD) are characterized by abnormal neurodevelopment, genetic, and environmental risk factors, as well as immune dysfunctions. Several lines of evidence suggest alterations in innate immune responses in children with ASD. To address this question in adults with high-functioning ASD (hf-ASD), we sought to investigate the role of natural killer (NK) cells in the persistence of ASD. Methods NK cells from 35 adults with hf-ASD were compared to that of 35 healthy controls (HC), selected for the absence of any immune dysfunctions, at different time-points, and over a 2-year follow-up period for four patients. The phenotype and polyfunctional capacities of NK cells were explored according to infectious stigma and clinical parameters (IQ, social, and communication scores). Results As compared to HC, NK cells from patients with hf-ASD showed a high level of cell activation (p < 0.0001), spontaneous degranulation (p < 0.0001), and interferon-gamma production (p = 0.0004), whereas they were exhausted after in vitro stimulations (p = 0.0006). These data yielded a specific HLA-DR+KIR2DL1+NKG2C+ NK-cell signature. Significant overexpression of NKG2C in hf-ASD patients (p = 0.0005), indicative of viral infections, was inversely correlated with the NKp46 receptor level (r = − 0.67; p < 0.0001), regardless of the IgG status of tested pathogens. Multivariate linear regression analysis also revealed that expression of the late-activating HLA-DR marker was both associated with structural language (r = 0.48; p = 0.007) and social awareness (r = 0.60; p = 0.0007) scores in adult patients with hf-ASD, while KIR2DL1 expression correlated with IQ scores (p = 0.0083). Conclusions This study demonstrates that adults with hf-ASD have specific NK-cell profile. Presence of NKG2C overexpression together with high-level activation of NK cells suggest an association with underlying pathogens, a hypothesis warranting further exploration in future studies.

Abstract
Background Lassa virus (LASV) is the etiologic agent of an acute hemorrhagic fever endemic in West Africa. Natural killer (NK) cells control viral infections in part through the interaction between killer cell immunoglobulin-like receptors (KIRs) and their ligands. LASV infection is associated with defective immune responses, including inhibition of NK cell activity in the presence of MHC-class 1+-infected target cells. Methods We compared individual KIR and HLA-class 1 genotypes of 68 healthy volunteers to 51 patients infected with LASV in Sierra Leone, including 37 survivors and 14 fatalities. Next, potential HLA-C1, HLA-C2, and HLA-Bw4 binding epitopes were in silico screened among LASV nucleoprotein (NP) and envelope glycoprotein (GP). Selected 10-mer peptides were then tested in peptide-HLA stabilization, KIR binding and polyfunction assays. Findings LASV-infected patients were similar to healthy controls, except for the inhibitory KIR2DL2 gene. We found a specific increase in the HLA-C1:KIR2DL2 interaction in fatalities (10/11) as compared to survivors (12/19) and controls (19/29). We also identified that strong of NP and GP viral epitopes was only observed with HLA-C molecules, and associated with strong inhibition of degranulation in the presence of KIR2DL+ NK cells. This inhibitory effect significantly increased in the presence of the vGP420 variant, detected in 28.1% of LASV sequences. Interpretation Our finding suggests that presentation of specific LASV epitopes by HLA-C alleles to the inhibitory KIR2DL2 receptor on NK cells could potentially prevent the killing of infected cells and provides insights into the mechanisms by which LASV can escape NK-cell-mediated immune pressure.

Abstract
The prevalent human ΔF508 mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) is associated with reduced bone formation and bone loss in mice. The molecular mechanisms by which the ΔF508-CFTR mutation causes alterations in bone formation are poorly known. In this study, we analyzed the osteoblast phenotype in ΔF508-CFTR mice and characterized the signaling mechanisms underlying this phenotype. Ex vivo studies showed that the ΔF508-CFTR mutation negatively impacted the differentiation of bone marrow stromal cells into osteoblasts and the activity of osteoblasts, demonstrating that the ΔF508-CFTR mutation alters both osteoblast differentiation and function. Treatment with a CFTR corrector rescued the abnormal collagen gene expression in ΔF508-CFTR osteoblasts. Mechanistic analysis revealed that NF-κB signaling and transcriptional activity were increased in mutant osteoblasts. Functional studies showed that the activation of NF-κB transcriptional activity in mutant osteoblasts resulted in increased β-catenin phosphorylation, reduced osteoblast β-catenin expression, and altered expression of Wnt/β-catenin target genes. Pharmacological inhibition of NF-κB activity or activation of canonical Wnt signaling rescued Wnt target gene expression and corrected osteoblast differentiation and function in bone marrow stromal cells and osteoblasts from ΔF508-CFTR mice. Overall, the results show that the ΔF508-CFTR mutation impairs osteoblast differentiation and function as a result of overactive NF-κB and reduced Wnt/β-catenin signaling. Moreover, the data indicate that pharmacological inhibition of NF-κB or activation of Wnt/β-catenin signaling can rescue the abnormal osteoblast differentiation and function induced by the prevalent ΔF508-CFTR mutation, suggesting novel therapeutic strategies to correct the osteoblast dysfunctions in cystic fibrosis.

Abstract
Boisson et al. report a human homozygous mutation of HOIP, the gene encoding the catalytic component of the linear ubiquitination chain assembly complex, LUBAC. The missense alleles impair the expression of HOIP, destabilizing the LUBAC complex and resulting in immune cell dysfunction leading to multiorgan inflammation, combined immunodeficiency, subclinical amylopectinosis, and systemic lymphangiectactasia. Inherited, complete deficiency of human HOIL-1, a component of the linear ubiquitination chain assembly complex (LUBAC), underlies autoinflammation, infections, and amylopectinosis. We report the clinical description and molecular analysis of a novel inherited disorder of the human LUBAC complex. A patient with multiorgan autoinflammation, combined immunodeficiency, subclinical amylopectinosis, and systemic lymphangiectasia, is homozygous for a mutation in HOIP, the gene encoding the catalytic component of LUBAC. The missense allele (L72P, in the PUB domain) is at least severely hypomorphic, as it impairs HOIP expression and destabilizes the whole LUBAC complex. Linear ubiquitination and NF-κB activation are impaired in the patient’s fibroblasts stimulated by IL-1β or TNF. In contrast, the patient’s monocytes respond to IL-1β more vigorously than control monocytes. However, the activation and differentiation of the patient’s B cells are impaired in response to CD40 engagement. These cellular and clinical phenotypes largely overlap those of HOIL-1-deficient patients. Clinical differences between HOIL-1- and HOIP-mutated patients may result from differences between the mutations, the loci, or other factors. Our findings show that human HOIP is essential for the assembly and function of LUBAC and for various processes governing inflammation and immunity in both hematopoietic and nonhematopoietic cells.

Abstract
Nuclear factor κB (NF-κB) essential modulator (NEMO), a regulatory component of the IκB kinase (IKK) complex, controls NF-κB activation through its interaction with ubiquitin chains. We show here that stimulation with interleukin-1 (IL-1) and TNF induces a rapid and transient recruitment of NEMO into punctate structures that are anchored at the cell periphery. These structures are enriched in activated IKK kinases and ubiquitinated NEMO molecules, which suggests that they serve as organizing centers for the activation of NF-κB. These NEMO-containing structures colocalize with activated TNF receptors but not with activated IL-1 receptors. We investigated the involvement of nondegradative ubiquitination in the formation of these structures, using cells deficient in K63 ubiquitin chains or linear ubiquitin chain assembly complex (LUBAC)-mediated linear ubiquitination. Our results indicate that, unlike TNF, IL-1 requires K63-linked and linear ubiquitin chains to recruit NEMO into higher-order complexes. Thus, different mechanisms are involved in the recruitment of NEMO into supramolecular complexes, which appear to be essential for NF-κB activation.

Abstract
The Notch signaling pathway is involved in liver development and regeneration. Here, we investigate the role of the 4 mammalian Notch paralogs in the regulation of hepatoblast proliferation and hepatocytic differentiation. Our model is based on bipotential mouse embryonic liver (BMEL) progenitors that can differentiate into hepatocytes or cholangiocytes in vitro and in vivo. BMEL cells were subjected to Notch antagonists or agonists. Blocking Notch activation with a γ-secretase inhibitor, at 50 μM for 48 h, reduced cell growth by 50%. S-phase entry was impaired, but no apoptosis was induced. A systematic paralog-specific strategy was set using lentiviral transduction with constitutively active forms of each Notch receptor along with inhibition of endogenous Notch signaling. This assay demonstrates that proliferation of BMEL cells requires Notch2 and Notch4 activity, resulting in significant down-regulation of p27(Kip1) and p57(Kip2) cyclin-dependent kinase inhibitors. Conversely, Notch3-expressing cells proliferate less and express 3-fold higher levels of p57(Kip2). The Notch3 cells present a hepatocyte-like morphology, enhanced multinucleation, and a ploidy shift. Moreover, Notch3 activity is conducive to hepatocytic differentiation in vitro, while its paralogs impede this fate. Our study provides the first evidence of a functional diversity among the mammalian Notch homologues in the proliferation and hepatocytic-lineage commitment of liver progenitors.

Abstract
The activity of Notch ligands is tightly regulated by trafficking events occurring both before and after ligand-receptor interaction. In particular endocytosis and recycling have been shown to be required for full signaling activity of the ligands before they encounter the Notch receptor. However little is known about the precise endocytic processes that contribute to ligand internalization. Here we demonstrate that endocytosis contributes to Dll1 signaling activity by preserving the ligand from shedding and degradation. We further show that the glycosphingolipid-binding motif originally identified in Drosophila Notch ligands is conserved in mammals and is necessary for Dll1 internalization. Mutation of its conserved tryptophan residue results in a Dll1 molecule which is rapidly inactivated by shedding and degradation, does not recycle to the cell surface and does not activate Notch signaling. Finally, silencing in the signal-sending cells of glucosylceramide synthase, the enzyme implicated in the initial phase of glycosphingolipid synthesis, down-regulates Notch activation. Our data indicate that glycosphingolipids, by interacting with Dll1, may act as functional co-factors to promote its biological activity.

Abstract
It was recently shown that individuals carrying the naturally occurring mutant CX3CR1-Ile(249)-Met(280) (hereafter called CX3CR1-IM) have a lower risk of cardiovascular disease than individuals homozygous for the wild-type CX3CR1-Val(249)-Thr(280) (CX3CR1-VT). We report here that peripheral blood mononuclear cells (PBMC) from individuals with the CX3CR1-IM haplotype adhered more potently to membrane-bound CX3CL1 than did PBMC from homozygous CX3CR1-VT donors. Similar excess adhesion was observed with CX3CR1-IM-transfected human embryonic kidney (HEK) cell lines tested with two different methods: the parallel plate laminar flow chamber and the dual pipette aspiration technique. Suppression of the extra adhesion in the presence of pertussis toxin indicates that G-protein mediated the underlying transduction pathway, in contrast to the G-protein-independent adhesion previously described for CX3CR1-VT. Surprisingly, HEK and PBMC that expressed CX3CR1-IM and -VT were indistinguishable when tested with the soluble form of CX3CL1 for chemotaxis, calcium release, and binding capacity. In conclusion, only the membrane-anchored form of CX3CL1 functionally discriminated between these two allelic isoforms of CX3CR1. These results suggest that each form of this ligand may lead to a different signaling pathway. The extra adhesion of CX3CR1-IM may be related to immune defenses and to atherogenesis, both of which depend substantially on adhesive intercellular events.

Abstract
We identified two novel isoforms of the human chemokine receptor CX3CR1, produced by alternative splicing and with N-terminal regions extended by 7 and 32 aa. Expression of the messengers coding these isoforms, compared with that of previously described V28 messengers, is lower in monocytes and NK cells, but higher in CD4(+) T lymphocytes. CX3CR1 and its extended isoforms were expressed in HEK-293 cells and compared for expression, ligand binding, and cellular responses. In steady state experiments, all three CX3CR1 isoforms bound CX3CL1 with similar affinity. In kinetic binding studies, however, k(on) and k(off) were significantly greater for the extended CX3CR1 isoforms, thereby suggesting that the N-terminal extensions may alter the functions induced by CX3CL1. In signaling studies, all three CX3CR1 isoforms mediated agonist-dependent calcium mobilization, but the EC(50) was lower for the extended than for the standard isoforms. In addition, chemotactic responses for these extended isoforms shifted left, also indicating a more sensitive response. Finally, the longer variants appeared to be more potent HIV coreceptors when tested in fusion and infection assays. In conclusion, we identified and characterized functionally two novel isoforms of CX3CR1 that respond more sensitively to CX3CL1 and HIV viral envelopes. These data reveal new complexity in CX3CR1 cell activation and confirm the critical role of the N-terminal domain of the chemokine receptors in ligand recognition and cellular response.

Abstract
P100, which is encoded by NF-kappa B2, inhibits Rel dimers. It can also be processed into p52, one of the DNA binding sub-units of NF-kappa B/Rel factors. Several p100 C-terminal truncations that result from gene rearrangements are associated with lymphomagenesis. Here, we characterized a new p100 mutant that we termed p100HB. It originates from a point-mutation that generates a premature stop-codon, and thus the protein lacks the last 125 amino acids. We have detected p100HB in several human tumor cell lines. The truncated protein is mainly unprocessed, and although it still binds Rel dimers, it has reduced inhibitory potency compared to p100 and translocates into the nucleus. Thus, p100HB may be associated with deregulated NF-kappa B/Rel functions.

Abstract
Expression of membrane-bound CX3CL1, a CX(3)C chemokine, can be strongly induced by inflammatory cytokines in primary endothelial cells, mediating capture and tight adhesion of cells, such as monocytes, that carry the CX(3)CR1 receptor. Here, we measured CX3CL1 mRNA and protein induction by human aortic smooth muscle cells (SMCs), another major component of vessel walls, in response to inflammatory stimuli, and analyzed the effect of membrane-bound CX3CL1 on monocyte adhesion, tissue factor (TF) expression, and tumor necrosis factor-alpha (TNF-alpha) released. In human vascular SMCs, CX3CL1 transcripts were induced after 4h of stimulation with a combination of TNF-alpha and interferon-gamma. Cell-associated and shedded CX3CL1 were measured with a specific ELISA, showing that only 30% of the protein was cleaved from the membrane. Expression of CX3CL1 by SMC increased adhesion of monocytic cells, an effect, which was blocked by soluble CX3CL1. Interestingly, monocyte adhesion to CX3CL1-coated plates partially inhibited lipopolysaccharide-induced TF expression and TNF-alpha release. Thus, CX3CL1, in addition to its adhesive/chemotactic functions, directly promotes monocyte antiinflammatory and antiprocoagulant responses. This could have important implications in clinical settings such as atherosclerosis, in which SMCs and monocytic cells are in close proximity.

Abstract
OBJECTIVE To evaluate the safety and effectiveness of a zonal-progressive multifocal silicone intraocular lens (IOL). DESIGN Prospective, nonrandomized, fellow eye comparative trial. PARTICIPANTS Four hundred fifty-six subjects were enrolled at 14 investigational sites in the United States; 400 subjects achieved 1-year follow-up. A subset of 123 subjects (102 at 1 year) were enrolled in a monofocal fellow eye control substudy; subjects were implanted with the multifocal IOL in one eye and a comparable monofocal IOL in the fellow eye. METHODS Cataract extraction and implantation of a zonal-progressive multifocal silicone IOL was performed using the surgeon's standard technique. Subjects were followed at six postoperative examination intervals through 1 year. MAIN OUTCOME MEASURES The key efficacy measures were mean uncorrected and corrected distance and near visual acuity at 1 year after surgery. RESULTS In the monofocal fellow eye control substudy, the multifocal eyes showed a mean 2-line increase over monofocal eyes for uncorrected and distance-corrected near visual acuity (P < 0.0001). Mean uncorrected distance visual acuity was similar between multifocal and monofocal eyes (P = 0.116). A significantly higher proportion of bilateral multifocal subjects reported that they could function comfortably without glasses at near (81%, 96 of 118) compared with multifocal/monofocal subjects (56%; 93 of 165; P < 0.001) and unilateral multifocal subjects (58%; 56 of 97; P < 0.001). Low-contrast visual acuity was reduced in multifocal eyes by approximately 1 Snellen line. However, no perceived disadvantages attributable to the reduction in low-contrast acuity were found. Although the perception of halos and glare increased in the multifocal eyes, good visual function remained, and nearly all subjects were satisfied with the results of their surgery. CONCLUSIONS In a large study that included a subset of subjects with paired eye compared with those with monofocal lenses, this zonal-progressive multifocal lens provided a high level of uncorrected and corrected distance vision, improved uncorrected and distance-corrected near vision, reduced spectacle dependency, and a high level of patient satisfaction despite some loss of low-contrast visual acuity and increased reports of halos and glare.

Abstract
To understand the role of NF-kappa B complexes in T cell development and activation, we have generated transgenic mice in which RelA and c-Rel complexes were selectively inhibited in the T-lineage cells by specific expression of a trans-dominant form of I kappa B alpha. Transgene expression did not affect the thymic development, but led to lowered numbers of splenic T cells and to a dramatic decrease in the ex vivo proliferative response of splenic T lymphocytes. Analysis of IL-2 and IL-2R alpha expression demonstrated that the perturbation of the proliferation response was not attributable to an abnormal expression of these genes. In contrast, expression of IL-4, IL-10, and IFN-gamma was strongly inhibited in the transgenic T cells. The proliferative deficiency of the transgenic T cells was associated with an increased apoptosis. These results point out the involvement of NF-kappa B/Rel family proteins in growth signaling pathways by either regulating proteins involved in the IL-2 signaling or by functionally interfering with the cell cycle progression.

Abstract
In order to understand the role of NF-kappaB in EBV transformation we have established stably transfected IkappaBalpha into lymphoblastoid cells. Two clones were obtained in which the loss of NF-kappaB binding activity correlated with the constitutive expression of the transgenic IkappaBalpha. Protein latency expression was determined by immunocytochemistry. Expression of surface markers, intracytoplasmic content of cytokines cell cycle analysis after BrdU incorporation and DNA staining with propidium iodide were studied by flow cytometry. Percentage of apoptotic cells was determined by in-situ labelling of DNA strand breaks. No significative changes in EBV latency nor in cell surface marker expression was found. In contrast, intracytoplasmic TNFalpha levels were strongly reduced in transfected clones. Furthermore, 30% of IkappaBalpha transfected cells were apoptotic after 8 h of TNFalpha treatment. This correlated with a strong reduction of BrdU incorporation after 24 h of TNFalpha treatment. No effect was seen with non transfected cells or with cells transfected with a control plasmid. Our results suggest that the TNFalpha gene could be one of the targets of NF-kappaB in EBV infected cells and that NF-kappaB protects EBV-infected cells from apoptosis induced by TNFalpha, which may favour the proliferative effect of this cytokine.

Abstract
RelA and RelB belong to the nuclear factor-kappaB (NF-kappaB-Rel) transcription factor family. Both proteins are structurally and functionally related, but their intracellular and tissue distributions are different. In resting cells, RelB is found mostly in the nucleus, whereas RelA is sequestered in the cytosol by protein inhibitors, among which IkappaBalpha is the dominant form in lymphocytes. Upon cellular activation IkappaBalpha is proteolyzed, allowing RelA dimers to enter the nucleus and activate target genes. To study the selectivity of gene regulation by RelA and RelB, we generated T cell lines stably expressing a dominant negative mutant of IkappaBalpha. We show that selective inhibition of RelA-NF-kappaB decreased induction of NFKB1, interleukin-2, and interleukin-2Ralpha genes but not c-myc. Transcription driven by the IkappaBalpha promoter was blocked by the transgenic IkappaBalpha; however, wild type IkappaBalpha was expressed in the transgenic cell clones but with much slower kinetics than that in control cells. Wild type IkappaBalpha expression was concomitant with RelB up-regulation, suggesting that RelB could be involved in transcription of IkappaBalpha through binding to an alternative site. These results indicate that RelB and RelA have both distinct and overlapping effects on gene expression.

Abstract
OBJECTIVE The authors measured functional status after bilateral implantation of a multifocal versus a monofocal intraocular lens (IOL). METHODS A retrospective, case-control study was done on 100 subjects implanted bilaterally with a silicone-optic foldable zonal progressive IOL under United States Food and Drug Administration Investigational Device Exemption protocol and 103 control subjects implanted bilaterally with a monofocal IOL of similar design who were matched on age and postoperative corrected distance acuity. The Cataract TyPE specification, a 17-item functional status instrument, was modified, validated, and administered via telephone interview. The measures of vision, functional status, and quality of life were compared between patients and controls. RESULTS The instrument was valid (Cronbach's alpha = 0.94) and correlated moderately (Pearson's r= 0.34) with Snellen acuity. Multifocal subjects were more likely than monofocal controls to never wear spectacles (41% vs. 11.7%; P < 0.001). Multifocal subjects rated their vision without spectacles significantly better than those with monofocal IOLs (9.0 vs. 7.9; P < 0.001). The difference was most significant in rating of near vision without spectacles (7.8 vs. 5.0; P < 0.001). Multifocal subjects reported less limitation in specific visual tasks without spectacles (0.3 vs. 0.8; P < 0.001, where 1.0 represents "slightly" limited). This difference was consistently observed in subscales related to distance vision activities (0.1 vs. 0.4; P < 0.001), near vision activities (0.6 vs. 1.4; P < 0.001), and social activities (0.1 vs. 0.6; P < 0.001). CONCLUSIONS In this study, subjects with bilateral multifocal IOLs reported better overall vision, less limitation in visual function, and less spectacle usage than monofocal controls.

Abstract
Nuclear factor-kappa B (NF-kappa B)/Rel proteins are inducible transcriptional regulators of numerous cellular genes. They are particularly abundant in lymphoid tissues and are thought to be critical for the transcription of genes involved in immune and inflammatory responses. We have reported previously that a nuclear NF-kappa B activity was present in freshly extracted human thymocytes in the absence of in vitro treatment of these cells. In the present report, we identified NF-kappa B proteins extracted from human thymocyte nuclei as being p50/p65 and p50/c-Rel complexes. Immunochemical and immunofluorescent staining of thymus sections using specific Abs allowed visualization of nuclear NF-kappa B proteins in both thymocytes and nonthymocyte cells. This detection suggested a preferential activation of p50/c-Rel in medullary thymocytes, whereas p50/p65 was present in both cortical and medullary regions of human thymus lobules. However, the intensity of p65 labeling was much higher in several thymocytes from the medulla. p65, p50, and c-Rel activities were found in both CD4- and CD8-positive thymocytes. These observations suggest that p65 and c-Rel complexes play distinct roles in gene expression and that both forms of NF-kappa B play critical roles during late stages of the intrathymic maturation of T cells.

Abstract
Nuclear factor-kappaB (NF-kappaB) is one of major component induced by tumor necrosis factor-alpha (TNF), and its role in the signaling of TNF-induced cell death remains controversial. In order to delineate whether the involvement of NF-kappaB activation is required for triggering of the apoptotic signal of TNF, we inhibited the nuclear translocation of this transcription factor in TNF-sensitive MCF7 cells by introducing a human MAD-3 mutant cDNA coding for a mutated IkappaB alpha that is resistant to both phosphorylation and proteolytic degradation and that behaves as a potent dominant negative IkappaB alpha protein. Our results demonstrated that the mutated IkappaB alpha was stably expressed in the transfected MCF7 cells and blocked the TNF-induced NF-kappaB nuclear translocation. Indeed, TNF treatment of these cells induced the proteolysis of only the endogenous IkappaB alpha but not the mutated IkappaB alpha. The nuclear NF-kappaB released from the endogenous IkappaB alpha within 30 min of TNF treatment was rapidly inhibited by the mutated IkappaB alpha. There was no significant difference either in cell viability or in the kinetics of cell death between control cells and the mutated IkappaB alpha transfected cells. Furthermore, electron microscopic analysis showed that the cell death induced by TNF in both control and mutated IkappaB alpha transfected cells was apoptotic. The inhibition of NF-kappaB translocation in mutated IkappaB alpha-transfected cells persisted throughout the same time course that apoptosis was occurring. Our data provide direct evidence that the inhibition of NF-kappaB did not alter TNF-induced apoptosis in MCF7 cells and support the view that TNF-mediated apoptosis is NF-kappaB independent.

Abstract
The nuclear factor kappa B (NF-kappa B) is a eukaryotic transcription factor. In B cells and macrophages it is constitutively present in cell nuclei, whereas in many other cell types, NF-kappa B translocates from cytosol to nucleus as a result of transduction by tumor necrosis factor alpha (TNF alpha), phorbol ester, and other polyclonal signals. Using neuroblastoma cell lines as models, we have shown that in neural cells NF-kappa B was present in the cytosol and translocated into nuclei as a result of TNF alpha treatment. The TNF alpha-activated NF-kappa B was transcriptionally functional. NF-kappa B activation by TNF alpha was not correlated with cell differentiation or proliferation. However, reagents such as nerve growth factor (NGF) and the phorbol ester phorbol 12-myristate 13-acetate (PMA), which induce phenotypical differentiation of the SH-SY5Y neuroblastoma cell line, activated NF-kappa B, but only in that particular cell line. In a NGF-responsive rat pheochromocytoma cell line, PC12, PMA activated NF-kappa B, whereas NGF did not. In other neuroblastoma cell lines, such as SK-N-Be(2), the lack of PMA induction of differentiation was correlated with the lack of NF-kappa B activation. We found, moreover, that in SK-N-Be(2) cells protein kinase C (PKC) enzymatic activity was much lower compared with that in a control cell line and that the low PKC enzymatic activity was due to low PKC protein expression. NF-kappa B was not activated by retinoic acid, which induced morphological differentiation of all the neuroblastoma cell lines used in the present study. Thus, NF-kappa B activation was not required for neuroblastoma cell differentiation. Furthermore, the results obtained with TNF alpha proved that NF-kappa B activation was not sufficient for induction of neuroblastoma differentiation.

Abstract
Using specific monoclonal and polyclonal antibodies, we have analyzed protein kinase C alpha and beta isozyme expression in human T cells from peripheral blood (PB) and from thymus. While the PKC beta isozyme was present in all T cell sub-types isolated from both PB and thymus, the alpha isozyme was found only in single positive CD4+ thymocytes, in PB-CD4+ lymphocytes and in PB-CD8+ T cells from several donors. It was absent from both, CD8+ and double positive CD4+/CD8+ thymocytes. These results show that PKC alpha and -beta are differentially regulated during intra-thymic development and suggest that PKC alpha plays a specific role in helper T cell function.

Abstract
NF-kB is a eukaryotic transcription regulatory factor. In T cells and T cell lines, NF-kB is bound to a cytoplasmic proteic inhibitor, the IkB. Treatment of T cells with mitogens (phorbol esters) or cytokines (TNF alpha) induces NF-kB nuclear translocation and the subsequent expression of NF-kB dependent T cell genes. Here we examined the activation of NF-kB in human T cell thymic progenitors. We report differences in (Ca2+)i requirement for NF-kB activation in thymocytes as compared to mature T cells. Furthermore, our results indicated that thymocytes have a constitutively active form of NF-kB, suggesting that they are activated in vivo.

Abstract
CD2 triggering of human T lymphocyte activation has been associated with the activation of different interacting protein kinases, including protein kinase C (PKC). However the precise roles of its phosphorylated substrates are still unknown. We show here that PKC-dependent and -independent pathways are responsible for the CD2-induced phosphorylation of stathmin, a ubiquitous soluble phosphoprotein, most likely acting as a general intracellular relay integrating various second messenger pathways. The phosphorylated variants of stathmin provide a fingerprint reflecting the second messenger pathway(s) stimulated. The respective roles of both PKC and stathmin in the regulation of T lymphocyte proliferation are discussed.

Abstract
In previous studies we demonstrated the triggering of the phospholipase C (PLC) pathway during the activation of an Ag-specific human CD4+ T lymphocyte clone by a mitogenic pair of CD2 (X11,D66) mAb. Similar conditions were applied to investigate a possible involvement of a phospholipase A2 (PLA2) acting as an additional alternative pathway during human T cell activation. Our results show that arachidonic acid or its derivatives are released after CD2 triggering. This release is largely independent of PLC activation and is mediated by a PLA2 because: 1) phosphatidylcholine is the preferential source of [3H]arachidonate release; 2) [3H]arachidonic acid release and phosphatidylcholine hydrolysis are blocked by two inhibitors of solubilized PLA2, mepacrine, and 4-p-bromophenacylbromide; and 3) we evidenced a PLA2 activity in cell homogenates. Extracellular calcium appears to play a critical role because the effects of CD2 mAb were inhibited in a Ca2(+)-depleted medium. In contrast, protein kinase C is not implicated since PMA, a protein kinase C activator, neither stimulated arachidonic acid release nor modulated CD2-induced arachidonic acid release. Cyclic AMP which has been proved to regulate the activity of the PLC in T lymphocytes does not appear to play an important role in the regulation of PLA2 activity since PGE2 has only a minimal effect on [3H]-arachidonate release. Altogether, these findings suggest that CD2 triggering stimulates a PLA2 activity in T lymphocytes via an extracellular Ca2(+)-dependent PLC protein kinase C independent mechanism.
