Abstract (original English)
Adipose tissue is a critical organ that plays a major role in energy balance regulation and the immune response through intricate signals. We report on the inter-relation between mature adipocytes and lymphocytes in terms of adipocyte-derived T-cell chemo-attractants and adipocyte metabolic effects on lymphocytes. During the culture time, mature adipocytes changed their structural and functional properties into de-differentiated cells. Isolated mature adipocytes expressed significantly higher levels of CIITA, major histocompatibility complex II (human leukocyte antigen [HLA]-DR) and costimulatory signal molecule CD80 compared with adipocytes after the de-differentiation process. Moreover, human leukocyte antigen-G, which may prevent the immune responses of mesenchymal stromal cells, was expressed at lower level in mature adipocytes compared with de-differentiated adipocytes. In line with these molecular data, functional results showed different immunoregulatory properties between adipocytes before and after the de-differentiation process. Mature adipocytes stimulated the proliferation of total lymphocytes and immunoselected cell populations CD3+, CD4+ and CD8+ in a direct contact-dependent way that involved the major histocompatibility complex I and II pathways. Moreover, adipocytes secreted potential chemo-attractant factors, but data showed that adipocyte-derived culture medi
