WebCD3 + CD20 + T cells are a population of CD3 + T cells co-expressing CD20 that make up to ∼3-5% of the CD3 + T-cell compartment in the peripheral blood of human beings. In … WebThe atypical T-cells have clear cytoplasm, and are associated with small lymphocytes, immunoblasts, plasma cells, and histiocytes. The abnormal cells are usually positive for CD3, CD4, CD10, and CD279 (PD-1), a phenotype characteristic of follicular T-helper cells. This relationship is also confirmed by recent gene expression profiling data.
WebCD3 ( cluster of differentiation 3) is a protein complex and T cell co-receptor that is involved in activating both the cytotoxic T cell (CD8+ naive T cells) and T helper cells (CD4+ naive T cells). It is composed of four distinct chains. In mammals, the complex contains a CD3γ chain, a CD3δ chain, and two CD3ε chains.
