Apr 4, 2023 · DoD IL4 overview. The Defense Information Systems Agency (DISA) is an agency of the US Department of Defense (DoD) that is responsible for developing and maintaining the DoD Cloud Computing Security Requirements Guide (SRG). The Cloud Computing SRG defines the baseline security requirements used by DoD to assess the security posture of a cloud ...

The interleukin 4 (IL4, IL-4) is a cytokine that induces differentiation of naive helper T cells (T h 0 cells) to T h 2 cells. Upon activation by IL-4, T h 2 cells subsequently produce additional IL-4 in a positive feedback loop.

IL-4 plays important roles in a myriad of cellular events, making it difficult to study its effects, particularly in vivo, on any one system. Although this review focuses on its neurological functions, most of what is known about IL4 comes from studies of peripheral immune cells, such as macrophages and lymphocytes.

STAT6 is so vital for the actions of IL-4 that Stat6-deficient mice phenocopy many of the defects observed with Il4- or Il4ra-deficient mice (e.g., related to Th2 differentiation and Ig class switch).

Mar 30, 2025 · IL4 is considered an important cytokine for tissue repair, counterbalancing the effects of proinflammatory type 1 cytokines, however, it also promotes allergic airway inflammation. Moreover, IL-4, a type 2 cytokine, mediates and regulates a variety of human host responses such as allergic, anti-parasitic, wound healing, and acute inflammation.

Sep 7, 2021 · Interleukin-4 (IL-4) is a four-α-helical bundle type I cytokine with broad pleiotropic actions on multiple lineages. Major actions of IL-4 were initially discovered for B and T cells, but this cytokine acts on more than a dozen different target cells spanning the innate and adaptive immune systems and is produced by multiple different cellular sources.

SNPs in IL4, IL13 and the receptor subunits are reportedly associated with glioma (111, 112). These polymorphisms highlight key features of IL-4/-13 receptor signaling that regulate disease susceptibility and severity, i.e. ligand binding, signaling and its regulation.

Jul 1, 2003 · Acute expression of the IL4 gene by differentiated T H 2 cells is regulated by many positive and negative inducible transcription factors, such as nuclear factor of activated T cells (NFAT ...

Interleukin-4 (IL4) is a growth factor for both B and T lymphocytes. - High levels of IL4Rs have been observed on tumors derived from such cells. - IL4Rs are also overexpressed on activated T lymphocytes, which mediate autoimmune disorders.

Interleukin-4 is a multifunctional cytokine that plays a critical role in the regulation of immune responses. Its effects depend upon binding to and signaling through a receptor complex consisting of the IL-4R alpha chain and the common gamma chain (gamma c), resulting in a series of phosphorylation events mediated by receptor-associated kinases.
