The IL-5 gene is located on chromosome 11 in the mouse, and chromosome 5 in humans, in close proximity to the genes encoding IL-3, IL-4, and granulocyte-macrophage colony-stimulating factor , [6] [7] which are often co-expressed in T h 2 cells. IL-5 is also expressed by eosinophils [8] and has been observed in the mast cells of asthmatic ...
Interleukin 4 (IL4) is produced by CD4 + T cells specialized in providing help to B cells to proliferate and to undergo class switch recombination and somatic hypermutation. Th2 cells, through production of IL-4, have an important function in B-cell responses that involve class switch recombination to the IgG1 and IgE isotypes.
The interleukin-5 receptor is a type I cytokine receptor.It is a heterodimer of the interleukin 5 receptor alpha subunit and CSF2RB. [1] [2]The IL-5 receptor (IL-5R) belongs to the type I cytokine receptor family and is a heterodimer composed of two polypeptide chains, one α subunit, which binds IL-5 and confers upon the receptor cytokine specificity, and one β subunit, which contains the ...
The eukaryotic cell cycle consists of four distinct phases: G 1 phase, S phase (synthesis), G 2 phase (collectively known as interphase) and M phase (mitosis and cytokinesis). M phase is itself composed of two tightly coupled processes: mitosis, in which the cell's nucleus divides, and cytokinesis, in which the cell's cytoplasm and cell membrane divides forming two daughter cells.
IL-4 - cytokine associated with the differentiation of mature T cells, which some B cell precursors are also responsive to. [5] IL-5 - cytokine that acts like IL-6, except it can also induce proliferation in B cells, and its effect on differentiation is partially inhibited by IL-4. IL-5 cannot induce differentiation in cells activated by anti ...
An inflammatory cytokine is a type of cytokine (a signaling molecule) that is secreted from immune cells and certain other cell types that promotes inflammation. Inflammatory cytokines are predominantly produced by T helper cells (T h) and macrophages and involved in the upregulation of inflammatory reactions. [1]
The protein encoded by this gene is an interleukin 5 specific subunit of a heterodimeric cytokine receptor. The receptor is composed of a ligand specific alpha subunit and a signal transducing beta subunit shared by the receptors for interleukin 3 (IL3), colony stimulating factor 2 (CSF2/GM-CSF), and interleukin 5 (IL5).
The cell cycle is a series of complex, ordered, sequential events that control how a single cell divides into two cells, and involves several different phases. The phases include the G1 and G2 phases, DNA replication or S phase, and the actual process of cell division, mitosis or M phase. [ 1 ]
