Abstract
Introduction In the US, despite the recent decline in breast cancer deaths, a persistent mortality disparity exists between black and white women with breast cancer, with black women having a 41% higher death rate. Several studies are now reporting that racial disparities can exist independent of socioeconomic and standard of care issues, suggesting that biological factors may be involved. Caveolin-1 (Cav1) loss in the tumor stromal compartment is a novel clinical biomarker for predicting poor outcome in breast cancer including triple negative subtype, however the mechanism of Cav1 loss is unknown. We previously identified miR-510-5p as a novel oncomir and propose here that the high levels observed in patients is a novel mechanism leading to stromal Cav1 loss and worse outcomes. Methods Cav1 was identified as a direct target of miR-510-5p through luciferase, western blot and qPCR assays. Stromal cross talk between epithelial cells and fibroblasts was assessed in vitro using transwell co-culture assays and in vivo using xenograft assays. Results We found that Cav1 is a direct target of miR-510-5p and that expression in fibroblasts results in an 'activated' phenotype. We propose that this could be important in the context of cancer disparities as we also observed increased levels of circulating miR-510-5p and reduced levels of stromal Cav1 in black women compared to white women with breast cancer. Finally, we observed a significant increase in tumor growth when tumor cells were co-injected with miR-510-5p expressing cancer associated fibroblasts in vivo. Conclusion We propose that miR-510-5p mediated negative regulation of Cav1 in fibroblasts is a novel mechanism of aggressive tumor growth and may be a driver of breast cancer disparity.

Abstract
CCK receptors are expressed on pancreatic cancer epithelial cells, and blockade with receptor antagonists decreases tumor growth. Activated pancreatic stellate cells or myofibroblasts have also been described to express CCK receptors, but the contribution of this novel pathway in fibrosis of the pancreatic cancer microenvironment has not been studied. We examined the effects of the nonselective CCK receptor antagonist proglumide on the activation, proliferation, collagen deposition, differential expression of genes, and migration in both murine and human PSCs. CCK receptor expression was examined using western blot analysis. Collagen production using activated PSCs was analyzed by mass spectroscopy and western blot. Migration of activated PSCs was prevented in vitro by proglumide and the CCK-B receptor antagonist, L365,260, but not by the CCK-A receptor antagonist L365,718. Proglumide effectively decreased the expression of extracellular matrix-associated genes and collagen-associated proteins in both mouse and human PSCs. Components of fibrosis, including hydroxyproline and proline levels, were significantly reduced in PSC treated with proglumide compared to controls. CCK peptide stimulated mouse and human PSC proliferation, and this effect was blocked by proglumide. These investigations demonstrate that targeting the CCK-B receptor signaling pathway with proglumide may alter the plasticity of PSC, rendering them more quiescent and leading to a decrease in fibrosis in the pancreatic cancer microenvironment.

Abstract
Geraniol is a bioactive component found in Palmarosa essential oil which has previously demonstrated good repellence to cattle ticks, mosquitoes and sand flies. The toxicity of geraniol to Dermanyssus gallinae, the most economically deleterious ectoparasite of laying hens in Europe, was studied in vitro in the laboratory. Exposure of D. gallinae to 0.5, 1 and 2% concentrations of geraniol (equating approximately to 0.02, 0.04 and 0.07 mg/cm2 geraniol, respectively) over a period of 24 hours resulted in 100% mortality of D. gallinae at all doses used.

Abstract
BACKGROUND Activated CD4+ T cells, mast cells and eosinophils are the main cytokine-producing cell-types infiltrating the conjunctiva during chronic allergic eye diseases. Interactions between these cells are thought to play an important immunopathogenic role in these disorders (giant papillary conjunctivitis; vernal keratoconjunctivitis; atopic keratoconjunctivitis). OBJECTIVE The objective was to compare the cytokine profiles of conjunctival T-cell lines from patients with different forms of chronic allergic eye disease. METHODS T cells were isolated from conjunctival biopsies and non-specifically expanded into lines. The lines were immunophenotyped by flow cytometry. Cytokine production was quantified by immunoassays and more sensitive molecular techniques were used to investigate cytokine mRNA expression to identify the presence of interleukin (IL) -2, IL-4 and interferon (IFN) -gamma transcripts. RESULTS Following four to six rounds of stimulation, the conjunctival T-cell populations were CD3+ (> 93%), with variable levels of CD4 and CD8 expression. All were HLA-DR+ (> 80%) with some HLA-DQ expression. Conjunctival T-cell lines from atopic keratoconjunctivitis produced selective increases in IFN-gamma, IL-10 and IL-13 (P<0.01), those from vernal keratoconjunctivitis produced increased IL-5 (P<0.01) whereas T-cell lines from giant papillary conjunctivitis produced only low levels of cytokines. IL-4 was only detected at the mRNA level and was expressed in four out of five T-cell lines in the vernal keratoconjunctivitis group. In contrast there was moderate to strong expression of IFN-gamma in five out of six T-cell lines in atopic keratoconjunctivitis. CONCLUSION Different patterns of T-cell cytokine profiles were observed for each disease, with low-level, non-polarized cytokine production in giant papillary conjunctivitis, a TH2-like profile in vernal keratoconjunctivitis and a shift towards a TH1-like profile in atopic keratoconjunctivitis.

Abstract
PURPOSE To compare cell types and cytokines in aqueous humor from patients with uveitis either occurring in association with a systemic disease or apparently isolated and not associated with a systemic disease. METHODS Cells were collected by centrifugation of fresh aqueous humor from uveitis and controls, and immunofluorescence techniques were performed with markers for T cells, B cells, and monocytes. Cytokines were measured in the aqueous supernatants, and serum samples were assayed for soluble interleukin-2 receptors. RESULTS When aqueous samples from idiopathic uveitis were compared with those from uveitis associated with a systemic disease, there were increases in CD3+, CD4+ (p = 0.001), and activated CD4+ T cells (p = 0.02) and a decrease in B cells (p = 0.0013). This was not reflected in the peripheral blood where there were no differences in the cell types or in soluble interleukin-2 receptor levels. No cells were obtainable from control aqueous. Interleukins-10 and -12, interferon-gamma, and transforming growth factor-beta2 were detected in aqueous supernatants. Interleukin-10 was reduced (p = 0.024) in uveitis in comparison with controls. CONCLUSIONS The results suggest a selective recruitment of CD4+ T cells within aqueous humor but only in idiopathic uveitis. In both disease groups there was a decrease in the immunoregulatory cytokine interleukin-10, which might enable an immune response to occur in an otherwise highly immunosuppressive microenvironment. Increases in activated CD4+ T cells combined with depressed interleukin-10 levels could partially explain why, for example, in acute anterior uveitis, the inflammatory disease is often more severe.

Abstract
Intermediate uveitis (IU) and Fuchs' heterochromic cyclitis (FHC) are two chronic ocular inflammatory disorders. They differ considerably in ocular morbidity, which is higher in IU. T cell lines were derived from the vitreous humour (VH) and peripheral blood (PB) of 10 patients with IU and four patients with FHC. There was a predominance of CD8+ in all the lines. However, there was a significantly higher percentage of CD4+ T cells in the T cell lines derived from VH of IU (32.0 +/- 8.6%) compared with FHC patients (19. 2 +/- 8.9%) (P = 0.04). The VH-derived T cell lines (VDTC) produced significantly higher levels of IL-2, interferon-gamma (IFN-gamma) and IL-10, but not IL-4, compared with PB-derived T cell lines (PBDTC) in both entities. There was significantly higher IL-2 production by VDTC from IU when compared with FHC patients (1810 +/- 220 pg/ml versus 518 +/- 94 pg/ml; P = 0.009), which could account for the more aggressive clinical features of this condition. In contrast IL-10 production was significantly higher by the VDTC from FHC compared with IU patients. The high IL-10 production by T cells infiltrating VH of FHC patients could down-regulate the inflammatory responses, thereby contributing to the benign clinical course seen in these patients. The accumulation of T cells with differing cytokine profiles in the VH suggests an important role for these cytokines in the pathogenesis of these chronic uveitides.

Abstract
To study the relation between the form of an Ag and the response to it, we compared presentation in vitro with hen egg lysozyme (HEL)-specific T cells from TCR transgenic mice of free HEL and liposome-encapsulated HEL by different APC. HEL-specific splenic B cells or bone marrow-derived dendritic cells were incubated with free HEL or HEL-containing liposomes targeted by Ab to either surface Ig, the Fc receptor, or MHC class I and II molecules. Ag presentation by HEL-specific B cells was at least 100-fold more efficient for HEL in surface Ig-targeted liposomes than free HEL taken up by the same receptor or HEL in liposomes targeted to class I or II molecules. Ag presentation by dendritic cells from Fc receptor-targeted vesicles was augmented 1,000-10,000-fold compared with free Ag or nontargeted liposomes, but presentation was also efficient when Ag was targeted to class I or II molecules. These results indicate that Ag-specific B cells and dendritic cells can be equally efficient in stimulating IL-2 production by Ag-specific T cells from unimmunized TCR transgenic mice when the Ag is multivalent and taken up by appropriate receptors. In contrast to B cells, which require engagement of surface Ig for optimal presentation, dendritic cells may present Ag by means of several different cell surface molecules.

Abstract
BACKGROUND The pathophysiology of chronic ocular allergic disease is not well understood. An eosinophil infiltrate is characteristic of such disease and eosinophil activity can be related to disease severity and to keratopathy, the most serious complication. Recently, eosinophils have been shown capable of cytokine production, particularly in allergic disease, although the disease-specific cytokine spectrum of tissue eosinophils is unknown. OBJECTIVES We sought to determine eosinophil numbers (absolute numbers and percentage of total leukocytes), cell surface antigen expression, and cytokine production in conjunctiva in chronic allergic eye disease and their relationship to corneal involvement. METHODS Ultrathin sections of conjunctiva were examined by tissue staining and by 1- and 2-color immunohistochemistry. RESULTS Eosinophil numbers were greater in giant papillary conjunctivitis (GPC) and vernal keratoconjunctivitis (VKC) and not related to corneal involvement. The eosinophil expression of the cell surface antigens intercellular adhesion molecule-1, CD4, IL-2R, and HLA-DR was greater in atopic keratoconjunctivitis (AKC) and VKC, the disorders with corneal disease, than in GPC, in which the cornea is not involved. For most cytokines, localization to eosinophils was greater for VKC and AKC than for GPC. RANTES, TGF-beta, and TNF-alpha localized to eosinophils in all disorders. Variations in the pattern of eosinophil-cytokine localization were found. In VKC IL-3, IL-5, IL-6, and GM-CSF were prominent; in GPC IL-5 was prominent; and in AKC IL-4, IL-8, and GM-CSF were prominent. CONCLUSIONS Chronic ocular allergic disorders affecting the cornea are distinguished from disorders that do not do so by greater expression of eosinophil surface antigens (which may imply greater cell activation) and differences in cytokine localization to eosinophils. These differences may be secondary to the variations in T-cell subsets or a primary phenomenon. Changes in eosinophil function, rather than cell numbers, may be important in clinical variations, such as keratopathy, and may allow future therapeutic exploitation.

Abstract
A single foot-pad immunization in adjuvant of BALB/c mice with non-modified BALB/c monoclonal antibodies (HyHEL 5, 9 and 10) specific for hen egg lysozyme permitted isolation of anti-idiotypic monoclonal antibodies 10 days later. An evaluation of different screening tests revealed that antibodies were detected more easily by isotype-specific or direct binding assays than by cross-linking ELISA procedures. These results were confirmed by a direct cell-binding assay on B cells transgenic for one of the immunizing antibodies. The use of these cells also permitted an evaluation of the ability of these antibodies to inhibit antigen binding under conditions in which the target antibody, in its cell-surface configuration, is minimally modified by potential artifacts induced by purification or fixation to a solid support. This study demonstrates that anti-idiotypic responses to anti-protein antibodies may be rapidly generated in syngeneic animals.

Abstract
Using single hormone-staining immunocytochemical methods, we have recently characterized a novel cell line, RC-4B/C, established from an aged male rat pituitary adenoma. This cell line contained all known anterior pituitary cell types including gonadotropes. Gonadotropin-releasing hormone receptors were also present. A recent re-examination of the cell types using single hormone stains showed that the cell line underwent an alteration in the percentage of different cell types as compared to the data obtained 2 years ago. The proportion of follicle-stimulating hormone-beta (FSH beta), luteinizing hormone-beta (LH beta), prolactin (PRL), and adrenocorticotropic hormone cells increased significantly (p less than or equal to 0.001), while the proportion of growth hormone (GH), and thyrotropin-beta cells did not change. Dual staining of the monolayers showed that the cell line contained many bihormonal cells producing FSH beta + LH beta, FSH beta + PRL and LH beta + PRL. The proportion of bihormonal FSH beta + LH beta and FSH beta + PRL cells was preponderant over monohormonal cells, while the proportion of bihormonal LH beta + PRL cells was in the same range as that of monohormonal cells. Preliminary data with dual labeling also revealed the presence of GH and PRL in the same cell, but complete absence of a combination such as FSH beta + GH. No search for the presence of other bihormonal or multihormonal cells was performed. In short, our data show that the majority of the cells in the cell line RC-4B/C contain FSH beta, LH beta and PRL and that among these cells many bihormonal cells are present.

Abstract
Pulsed electromagnetic fields (PEMFs) of certain configuration have been shown to be effective clinically in promoting the healing of fracture nonunions and are believed to enhance calcification of extracellular matrix. In vitro studies have suggested that PEMFs may also have the effect of modifying the extracellular matrix by promoting the synthesis of matrix molecules. This study examines the effect of one PEMF upon the extracellular matrix and calcification of endochondral ossification in vivo. The synthesis of cartilage molecules is enhanced by PEMF, and subsequent endochondral calcification is stimulated. Histomorphometric studies indicate that the maturation of bone trabeculae is also promoted by PEMF stimulation. These results indicate that a specific PEMF can change the composition of cartilage extracellular matrix in vivo and raises the possibility that the effects on other processes of endochondral ossification (e.g., fracture healing and growth plates) may occur through a similar mechanism.

Abstract
The demonstration of histochemical characteristics in calcifying cartilage is fraught with methodological difficulties including the distinction of mineralized from unmineralized cartilage and the demonstration of cell detail in relatively hard tissue. This study uses the decalcified bone matrix-induced enchondral (endochondral) ossification system to demonstrate a technique of methylmethacrylate embedding, thin sections, and a combination of histochemical stains that distinguishes mineralized from unmineralized cartilage while preserving excellent cell detail. These techniques are applicable to other areas of enchondral ossification and are exemplified by the staining of growth plates.

Abstract
We have described previously the isolation and characterization of five distinct subpopulations of tumor cells from a single spontaneous strain BALB/cfC3H mouse mammary tumor (Cancer Res., 38: 3174--3181, 3758--3763, 1978). Subpopulations 68H and 4.10 are polygonal and grow in epithelioid patterns in vitro, whereas subpopulations 66, 67, and 168 are fusiform and grow in lattice or fibroblast-like patterns. Line 4.10 produces tumors with distinctly glandular architecture, whereas the other four subpopulations produce poorly differentiated tumors with mixed epithelial-sarcomatous histological patterns. All five lines were evaluated for epithelial characteristics. Dome formation, characteristic of transporting epithelial cells, could be induced by dexamethasone or dimethyl sulfoxide only in line 4.10 cells. Antibodies to cell type-specific mammary epithelial antigens reacted with each of the subpopulations. All five subpopulations had ultrastructural features of epithelial cells, including desmosomes (all five lines), junctional complexes (68H, 4.10, early-passage 66 and 67 only; poorly defined in 168), and growth in cords demonstrating polarity (68H cells). Less definitive myoepithelial characteristics were also seen in four of the lines, including an incomplete reaction for Na+-K+-ATPase (4.10 cells), hemidesmosome-like junctions (168 and early-passage 66 cells), and pinocytotic vesicles at lower than normal frequency (66, 67, and 168 cells). Thus, none of the lines were distinctly myoepithelial. We conclude that the five subpopulations are epithelial cells that express a spectrum of epithelial characteristics.

Abstract
Fallopian tube carcinoma is one of the rarest of primary gynecologic malignancies. Normal tubal epithelium is composed of secretory, ciliated, and intercalary cells. To determine the cellular composition and ultrastructural details of this rare neoplasm, a moderately well-differentiated tubal carcinoma was studied with the electron microscope. A prominent feature was the formation of numerous ultramicro alveolar spaces lined by cell surface microvilli. The nuclei of the neoplastic cells demonstrated a variety of fine structural abnormalities. Based on cell size and shape criteria, a possible dual tumor cell population was suggested. However, no cilia were seen in any of the tumor cells and almost all were devoid of secretory granules. These latter observations suggest that this tumor was primarily a proliferation of intercalary cells.

Abstract
Thyroid glands of 36 chickens of the obese strain with hereditary spontaneous autoimmune thyroiditis were examined by electron microscopy at 1, 3, 5, 7, 10, and 14 weeks of age with particular emphasis on basal lamina changes. All chickens were of the B1B1 genotype. The electron microscopic results were compared with six normal White Leghorn chickens of the same age. The major abnormality observed in obese strain chickens was the persistent presence of electron-dense deposits along the follicular basal lamina in the thyroid beginning with 7-week-old chickens. The deposits morphologically comparable to immune complexes were noted either between the basal plasma membrane and the follicular basal lamina or below the follicular basal lamina. In 14-week-old chickens, the electron-dense deposits were observed within abnormally thickened basal lamina. The deposits were not present in the vascular basal lamina adjacent to the thyroid follicles and were not observed in the thyroids of 1- to 5-week old chickens and were also not encountered in normal White Leghorn chickens. Indirect morphologic evidence suggests that these may be antigen-antibody complexes, but characterization of these deposits and their role remain to be determined.
