The secondary structural features of IL-13 are similar to that of Interleukin 4 (IL-4); however it only has 25% sequence identity to IL-4 and is capable of IL-4 independent signaling. [ 7 ] [ 4 ] [ 8 ] IL-13 is a cytokine secreted by T helper type 2 (Th2) cells, CD4 cells, natural killer T cell , mast cells , basophils , eosinophils and ...
Activated STAT6 molecules form dimers which translocate to the nucleus to bind responsive elements (e.g. CD23 promoter in B cells, [12] arginase1 enhancer in macrophages [13]) The binding affinity of IL-4 for IL-4Rα is much higher than IL-13 for the IL-13Rα1, hence IL-4 would out-compete IL-13 for receptor availability within IL4R2 at parity ...
Interleukin-13 receptor subunit alpha-2 (IL-13Rα2), also known as CD213A2 (cluster of differentiation 213A2), is a membrane bound protein that in humans is encoded by the IL13RA2 gene. [ 5 ] Function
Interleukin 13 receptor, alpha 1, also known as IL13RA1 and CD213A1 (cluster of differentiation 213A1), is a human gene. [5] The protein encoded by this gene is a subunit of the interleukin 13 receptor. This subunit forms a receptor complex with IL4 receptor alpha, a subunit shared by IL13 and IL4 receptors.
When seeking approval for a drug, manufacturers can apply to the FDA for priority review. This is granted when a drug is intended to treat a serious condition and would "provide a significant improvement in safety or effectiveness" over currently available treatments. [1] A priority review voucher can be used when a drug does not fit these ...
Once a drug receives fast track designation, early and frequent communication between the FDA and a drug company is encouraged throughout the entire drug development and review process. The frequency of communication assures that questions and issues are resolved quickly, often leading to earlier drug approval and access by patients.
The documentation required in an NDA is supposed to tell "the drug’s whole story, including what happened during the clinical tests, what the ingredients of the drug are, the results of the animal studies, how the drug behaves in the body, and how it is manufactured, processed and packaged.” [2] Once approval of an NDA is obtained, the new ...
In the fields of medicine, biotechnology, and pharmacology, drug discovery is the process by which new candidate medications are discovered. [1] Historically, drugs were discovered by identifying the active ingredient from traditional remedies or by serendipitous discovery, as with penicillin.
