Generally speaking, the cell cycle regulation of meiosis is similar to that of mitosis. As in the mitotic cycle, these transitions are regulated by combinations of different gene regulatory factors, the cyclin-Cdk complex and the anaphase-promoting complex (APC). [1]
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 ...

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 name "interleukin" was chosen in 1979, to replace the various different names used by different research groups to designate interleukin 1 (lymphocyte activating factor, mitogenic protein, T-cell replacing factor III, B-cell activating factor, B-cell differentiation factor, and "Heidikine") and interleukin 2 (TSF, etc.).
A yeast meiocyte that is undergoing meiosis must pass through a number of checkpoints in order to complete the cell cycle. [3] If a meiocyte divides and this division results in a mutant cell, the mutant cell will undergo apoptosis and, therefore, will not complete the cycle.
The G2 to M transition is dramatic; there is an all-or-nothing effect, and the transition is irreversible. This is advantageous to the cell because entering mitosis is a critical step in the life cycle of a cell. If it does not fully commit, the cell would run into many issues with partially dividing, ultimately likely leading to the cell's death.
It is the stage of the life cycle when a cell gives rise to haploid cells each having half as many chromosomes as the parental cell. Two such haploid gametes, ordinarily arising from different individual organisms, fuse by the process of fertilization, thus completing the sexual cycle. Meiosis is ubiquitous among eukaryotes.
