WebCytokines are a broad and loose category of small proteins (~5–25 kDa [1]) important in cell signaling. Cytokines are peptides and cannot cross the lipid bilayer of cells to enter the cytoplasm. Cytokines have been shown to be involved in autocrine, paracrine and endocrine signaling as immunomodulating agents. WebDifferential expression of cell surface and intracellular markers, as well as their distinct immunoglobulin and cytokine secretion profiles, provide valuable clues to the diverse nature and function of the different B cell subsets.
