Web28 feb. 2024 · Following TCR ligation, tyrosine kinase ITK (interleukin-2-inducible T-cell kinase) is recruited to PIP3-rich membranes in which ITK interacts with the SLP76/LAT complex and is activated by Lck; then, the activated ITK interacts with and activates PLC-γ1, which in turn catalyses PIP2 to produce the second messengers IP3 and DAG that … WebIt is striking that TCR engagement profoundly, although transiently, desensitizes the IL-4 receptor. Within 1 h of stimulation through the TCR, phosphorylation of IL-4Rα, JAK1, Stat6, and IRS-2 is strikingly attenuated. The failure of such cells to respond to IL-4 lasts for ∼8 h, after which the cells regain their capacity to respond.
