Cytokines typically activate second messenger systems, like JAK-STAT pathways, as illustrated on the left side of the diagram. Conversely, hormones typically activate different signaling pathways, like G protein-coupled receptors, seen at the top of the figure.
Cytokinesis illustration Ciliate undergoing cytokinesis, with the cleavage furrow being clearly visible.. Cytokinesis (/ ˌ s aɪ t oʊ k ɪ ˈ n iː s ɪ s /) is the part of the cell division process and part of mitosis during which the cytoplasm of a single eukaryotic cell divides into two daughter cells.
The cytokinin zeatin is named after the genus of corn, Zea.. Cytokinins (CK) are a class of plant hormones that promote cell division, or cytokinesis, in plant roots and shoots.
Interleukin 3 (IL3) is a cytokine that regulates hematopoiesis by controlling the production, differentiation and function of granulocytes and macrophages. [ 15 ] [ 16 ] The protein, which exists in vivo as a monomer, is produced in activated T cells and mast cells, [ 15 ] [ 16 ] and is activated by the cleavage of an N-terminal signal sequence.
Cytokines are signals used in the immune system for intercellular communication. There are many cytokines that affect megakaryocytes. Certain cytokines such as IL-3 , IL-6 , IL-11 , LIF , erythropoietin , and thrombopoietin all stimulate the maturation of megakaryocytic progenitor cells. [ 9 ]
Lymphokines are a subset of cytokines that are produced by a type of immune cell known as a lymphocyte. [1] They are protein mediators typically produced by T cells to direct the immune system response by signaling between its cells.
HMGB1 can also induce dendritic cell maturation via upregulation of CD80, CD83, CD86 and CD11c, and the production of other pro-inflammatory cytokines in myeloid cells (IL-1, TNF-a, IL-6, IL-8), and it can lead to increased expression of cell adhesion molecules (ICAM-1, VCAM-1) on endothelial cells.

Mechanism of class-switch recombination that allows isotype switching in activated B cells. Immunoglobulin class switching, also known as isotype switching, isotypic commutation or class-switch recombination (CSR), is a biological mechanism that changes a B cell's production of immunoglobulin from one type to another, such as from the isotype IgM to the isotype IgG.
