Distinct antigenic loci are present within the human glomerulus as demonstrated by high resolution epifluorescent and phase-contrast microscopic techniques using affinity-purified antibody to characterized collagens. Type IV mouse tumor procollagen and type V collagen are present within the mesangium and along the endothelial aspect of the glomerular basement membrane, demonstrating antigenic continuity between these two glomerular zones. In contrast, antiserum to type IV collagen from bovine lens capsule reacts with the full thickness of the glomerular basement membrane, as well as in the tubular basement membrane and Bowman's capsule. Types I procollagen and collagen are found within the epithelium; and types III collagen and procollagen are not detected within the glomerulus. The functional role of the multiple distinct "basement membrane" collagens in the glomerular capillary wall is unknown. A complex structure is suggested, especially in the mesangial-subendothelial continuity, and in the differential localization of two forms of type IV collagen within the glomerular basement membrane.

Our study tries by immunofluorescence to specify the nature of the connective tissue of the breasts, and especially of the scaffolding of the fatty tissue and the matrix of the lobules and of the lactiferous ducts. In consists of a study of 35 samples which were taken from 13 women whose ages ranged from 40 to 75 and whose breasts were considered on clinical examination and on radiography as normal or abnormal. We have analyzed the distribution of anti-collagen types I, III, IV and V and anti-fibronectin and anti-laminin antibodies in certain sites in the breast which were chosen because of the diversity of forms they could take from one woman to another. In each case of the distribution of protein markers seemed to be regular without, as can be found in certain cases of scar or tumour formation, a change in the distribution of the matrix proteins. Therefore, as already suggested by certain histologists, benign abnormal breast conditions (fibrosis) should be considered as simple variations from the normal. This conclusion agrees with classical histological findings. [less ▲]

Using the most sensitive immunocytochemical method available, on ultrathin frozen sections, the results in this paper demonstrate that bovine placental lactogen (bPL) is present in the earliest fetal binucleate cells found at 21 days post coitum in the trophectoderm. A second protein, the SBU-3 antigen, which is absent in the early stages of pregnancy appears abruptly in the binucleate cell granules at 30 days post coitum coincident with the start of villus development. Subsequently, the granules contain both bPL and the SBU-3 antigen. This sequential production of unlike proteins indicates that the binucleate cell has different functions depending on the stage of pregnancy and has important roles to play both at implantation and in villus development.

Active neutrophil myeloperoxidase (MPO) is a powerful producer of oxidant molecules in acute or chronic inflammation, and it is essential to measure its activity in biological samples. We combined two immunological techniques, the SIEFED (specific immunologic extraction followed by enzymatic detection) and an ELISA, to measure the active and total contents of human MPO on the same sample and with the same calibration curve, to define an accurate ratio between the active and total enzyme. After the extraction of MPO from aqueous or biological samples by immobilized anti-MPO antibodies followed by a washing to eliminate unbound material, the active and the total contents of the enzyme were sequentially measured without interferences (patent: EP2017351-B1, 2010). Compared to a classical sandwich ELISA, there is one additional step corresponding to the in situ measurement of MPO activity, but this step does not affect the following measurement of the total MPO content. After validation, the combined technique was applied to a whole blood model of in vitro stimulation with phorbol-myristate-acetate (PMA), cytochalasin B/N-formyl-methionyl-leucyl-phenyl-alanine (CB/fMLP) or lipopolysaccharide/ tumor necrosis factor-alpha (LPS/TNF-α) (n=9). The active/total MPO ratio in whole blood reached 0.267±0.126 for non-stimulated condition and was significantly (p<0.05) higher for PMA (0.360±0.106), CB/fMLP (0.380±0.113) and LPS/TNF-α (0.432±0.124) stimulated conditions. These different ratios highlight the real oxidant potential of MPO, which depends on the stimulating conditions, witness of what could happen in pathological situations with diagnostic purpose. The combined SIEFED/ELISA method also appeared as a powerful tool to screen potential inhibitors that could interact directly with the enzyme, either on its active site or on another key position.

We investigated possible immunological changes in 15 professional football players before, during and after the sports season. We studied the leucocyte count as well as different functions such as T-lymphocyte proliferation, NK activity, chemotaxis and phagocytosis of neutrophils. Training and competitions did not produce any change in the total number of leucocytes but increased neutrophil counts and decreased T4 lymphocyte counts. We also observed a slight decrease of T-lymphocyte proliferation and a significant decrease of neutrophil functions. On the other hand, training and competitions did not induce significant changes in the number of NK cells nor in the total NK cytotoxic activity. The different change observed tended to normalize after the sports season. Our results suggest a predominant neutrophil function depression in football players during a training season which could partly explain the susceptibility of elite athletes to infections. [less ▲]

Thymus dysfunction, especially immune suppression, is frequently associated with various virus infections.Whether viruses may disturb the thymus function and play a role in the pathogenesis of autoimmune diseases is an open issue. Enteroviruses, especially Coxsackievirus B4 (CV-B4), have been largely suggested as potential inducers or aggravating factors of type 1 diabetes (T1D) pathogenesis in genetically predisposed individuals. Several pathogenic mechanisms of enterovirus-induced T1D have been suggested. One of these mechanisms is the impairment of central self-tolerance due to viral infections. Coxsackievirus-B4 is able to infect murine thymus in vitro and in vivo and to infect human thymus in vitro. Thymic epithelial cells and thymocytes are targets of infection with this virus, and several abnormalities, especially disturbance of maturation/differentiation processes, were observed.Altogether, these data suggest that CV-B infection of thymus may be involved in the pathogenesis of T1D. Further investigations are needed to explore this hypothesis. [less ▲]
