Essay

The dissertation covers the studies of CD150 expression and CD150-mediated signaling pathways in lymphoma cells originated from B lymphocytes. CD150 is co-expressed with SH2D1A adaptor protein in lymphoma cells with activated B cell phenotype, such as Hodgkin's lymphoma and ABC-type diffuse large B cell lymphoma (ABC-DLBCL). It was found that malignant cells in classical Hodgkin's lymphoma express membrane and soluble splice isoforms of CD150 receptor on mRNA level. In malignant B cells, Akt and MAPK (ERK1/2, JNK2, p38MAPK) signaling pathways are regulated via CD150 receptor. SH2D1A adaptor protein, Syk, Lyn and Btk tyrosine kinases are involved in regulation of CD150-mediated signaling.
