Growing role of S100B protein as a putative therapeutic target for neurological- and nonneurological-disorders. Neurosci Biobehav Rev 2021; 127:446-458. [PMID: 33971224 DOI: 10.1016/j.neubiorev.2021.04.035] [Citation(s) in RCA: 19] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2021] [Revised: 04/15/2021] [Accepted: 04/29/2021] [Indexed: 02/07/2023]
Abstract
S100B is a calcium-binding protein mainly expressed by astrocytes, but also localized in other definite neural and extra-neural cell types. While its presence in biological fluids is widely recognized as a reliable biomarker of active injury, growing evidence now indicates that high levels of S100B are suggestive of pathogenic processes in different neural, but also extra-neural, disorders. Indeed, modulation of S100B levels correlates with the occurrence of clinical and/or toxic parameters in experimental models of diseases such as Alzheimer's and Parkinson's diseases, amyotrophic lateral sclerosis, muscular dystrophy, multiple sclerosis, acute neural injury, inflammatory bowel disease, uveal and retinal disorders, obesity, diabetes and cancer, thus directly linking the levels of S100B to pathogenic mechanisms. In general, deletion/inactivation of the protein causes the improvement of the disease, whereas its over-expression/administration induces a worse clinical presentation. This scenario reasonably proposes S100B as a common therapeutic target for several different disorders, also offering new clues to individuate possible unexpected connections among these diseases.

Abstract
We report on an uncommon laryngeal non-Langerhans cell histiocytosis. An 11-year-old boy presented with a 6 months history of progressive breath inhibition. Magnetic resonance imaging showed diffuse laryngeal and local lymph node swelling. Histology first resembled sarcoidosis, however, corticosteroids were ineffective. Lymphoma, infection, immunodeficiency, and autoimmune disease were excluded. Six months later, biopsies were repeated, now showing numerous ectatic lymph vessels with clusters of histiocytes bearing stellate extensions and emperipolesis. S100 protein and CD1a were negative. Indomethacin treatment led to a gradual improvement. In conclusion, we observed a nonmalignant non-Langerhans cell endolymphatic reticulohistiocytosis, not fitting into any of the described categories.

Abstract
Vascular repair by adult hematopoietic stem cells (HSCs) is well-appreciated because these cells are known for their plasticity. We have shown that adult HSCs differentiate into endothelial cells and participate in both retinal and choroidal neovascularization. We asked whether HSCs participated in the wounding response by forming astrocytes, retinal pigment epithelia (RPE), macrophages, and pericytes. Lethally irradiated C57BL6/J mice were reconstituted with HSCs from mice homozygous for green fluorescent protein (GFP) and then subjected to laser-induced rupture of Bruch's membrane. After immunohistochemical examination of ocular tissue, GFP(+) astrocytes were observed concentrated along the edge of the laser wound, where they and mural cells closely ensheathed the neovasculature. GFP(+) vascular endothelial cells and macrophages/microglia were also evident. Large irregularly shaped GFP(+) RPE cells constituted approximately 93% of RPE cells adjacent to the edge of the denuded RPE area. In regions farther away from the wound, GFP(+) RPE cells were integrated among the GFP(-) host RPE. Thus, postnatal HSCs can differentiate into cells expressing markers specific to astrocytes, macrophages/microglia, mural cells, or RPE. These studies suggest that HSCs could serve as a therapeutic source for long-term regeneration of injured retina and choroid in diseases such as age-related macular degeneration and retinitis pigmentosa.

Abstract
Feline immunodeficiency virus (FIV) is the feline analog of human immunodeficiency virus and a small animal model of human acquired immune deficiency syndrome (AIDS). We sought to identify early in vivo target cells in cats infected with clade B or C FIV. In tissues, however, neither mouse monoclonal nor rabbit polyclonal antibodies suitably detected FIV because of either insensitivity or lack of specificity. We therefore developed an immunohistochemical protocol using high-antibody-titer serum from cats chronically infected with FIV(Petaluma). Native species anti-FIV antibodies were labeled with biotinylated protein A before placement on tissues, and downstream signal was tyramide-amplified. This method revealed many productively infected cells in bone marrow, lymph node, thymus, mucosal-associated lymphoid tissue, and spleen, but few such cells in liver and none in kidney or brain. Concurrent labeling for virus and cell phenotype revealed that antigen-bearing populations were primarily T lymphocytes but included macrophages and dendritic cells. Our results demonstrate that FIV: 1) expands rapidly in T cells, 2) targets long-lived reservoir populations, and 3) is replicatively quiescent in brain at 3 weeks after infection. Use of native species antibodies for immunohistochemical detection of infectious antigens has application to other settings in which xenotypic (eg, mouse and rabbit) antibody sources are inadequate or unavailable.

Abstract
The staining patterns of the monoclonal antibodies S-100 and Melan-A in canine melanoma were assessed based on cytological specimens of six canine melanomas (four benign, two malignant). In addition, eight regional lymph nodes of the two dogs with malignant melanomas were stained using these markers. For reference, all specimens were also evaluated immunohistochemically using S-100 and Melan-A. To assess the immunocytochemical specificity of both antibodies, various canine tumours and normal tissues were stained. The immunocytochemical staining results of the canine melanomas and the regional lymph nodes showed high conformity with the immunohistochemical reactivity patterns for S-100 and Melan-A. The specificity of Melan-A was higher compared with S-100. Melan-A, in particular, may be helpful for the cytological diagnosis of canine melanoma.

Abstract
CORP-4 is a cell line obtained in our laboratory from an explanted human bladder carcinoma. This cell line shows certain dendritic cell features such as adherence to the culture plate surface, a doubling time of 24 h and an enzymatic profile typical of cells involved in antigen presentation (non-specific esterases, lysozyme and alpha-1-antitrypsin). Its phenotypic analysis revealed CD 15 and Fc receptor expression, S-100 surface protein and the presence of positive reactivity to different lectins such as Concanavalin A (Con A) and Peanut agglutinin (PNA). CORP-4 was found to be a non-phagocytic cell line after it was assayed with latex, and FcR- and C3bR-mediated phagocytosis. Furthermore, CORP-4 produced interleukin-1 (IL-1) as determined by thymocyte proliferation assays and also fixes immune complexes in a non-complement dependent fashion. HLA class I and class II antigens were inducible by both 5 azacytidine and gamma interferon.

Abstract
A comparative immunohistologic study of the cell density and distribution pattern of follicular dendritic reticulum cells (DRCs) within their follicular microenvironments (germinal centers and mantle zones) was performed by immunoperoxidase technique with a selected panel of antibodies either operationally specific for DRCs (DRC-1) or reported as having additional immunoreactivity with DRCs (antibodies to B- and T-cells, leukocytes, monocytes/macrophages, desmosomal components, and S-100 protein). Twenty-five biopsy specimens, including reactive lymph nodes and tonsils as well as normal spleen tissue, were analyzed. Serial frozen sections were tested either with single antibodies or paired monoclonal reagents in double-labeling procedures. Our results consistently indicated that DRCs positive for Leu M3 and BA-2 antibodies were confined to the central portion of germinal centers, whereas DRCs immunoreactive for S-100 protein and desmoplakin 1 and 2 were localized mostly in the central and pericentral portion of germinal centers. All the DRCs extending from the central portion of germinal centers to the mantle zones were labeled with DRC-1 and, unexpectedly, with OKB7 antibodies. Other immunostainings, such as those for HLA-DR antigens, common leukocyte antigen, and Leu 3a, were not contributory in defining topographic differences of DRCs within the follicle. The consistent heterogeneity of the labeling patterns appears to suggest a possible in situ immunophenotypic grouping of DRCs, and the concept of their possible heterogeneity appears to be corroborated.

Abstract
We used a panel of monoclonal and polyclonal antibodies to analyze frozen and paraffin-embedded lymph node biopsy specimens from 25 intravenous drug abusers (IVDA) with acquired immunodeficiency syndrome (AIDS)-related lymphadenopathy histologically characterized by follicular hyperplasia. Our aim was to obtain diagnostic clues to this commonly occurring pattern. Double-labelling immunohistological studies were also performed on selected frozen sections and 13 plastic-embedded specimens were tested by a number of enzyme reactions. Consistent features in IVDA included abnormally high numbers of intrafollicular T-cells, positive for acid phosphatase and beta-glucuronidase, most of which had Leu-2a-positive phenotype; a marked reduction or loss of mantle zone B-cells (positive for surface IgD-IgM and alkaline phosphatase); and disarray of the network of follicular dendritic reticulum cells (DRCs), as revealed with DRC-1 and anti-S-100 protein antibodies or with reaction for 5'-nucleotidase. When present, distinctive intrafollicular clusters of Leu-2a-positive T-cells and mantle zone B-cells were nearly always associated with areas lacking DRCs in some patients. The intrafollicular hypervascularity invariably found in IVDA proved to be of a true capillary nature, as demonstrated by alkaline phosphatase, 5'-nucleotidase, and ATPase reactions. In control tissues, all showing absence of Leu-2a-positive intrafollicular T-cells, most of the above individual changes could be detected, although they were occasional, mild, and never associated within the same follicle. By contrast, combined immunohistological and enzyme histochemical findings in IVDA indicated that in most follicles such changes were marked and very often associated within the same follicle in each case. It can be concluded that on the basis of a combined analysis of lymphoid and non-lymphoid follicular constituents, the histological changes of AIDS-related lymphadenopathy with follicular hyperplastic pattern are further defined and corroborated.
