Transforming Growth Factor-Beta (TGF-β) signaling pathway plays a pivotal role in orchestrating various cellular processes, ranging from embryonic development to tissue homeostasis and immune resp

Almost all of the TGF-β in a tissue is already there, and almost none of it is active. That single fact reorganises how the pathway should be studied. Unlike most cytokines, TGF-β is deposited into t

PI3K does not switch on a protein — it rewrites a membrane. Everything downstream follows from one chemical event: the 3-hydroxyl of a phosphoinositide is phosphorylated, PIP₂ becomes PIP₃, and every

Cell culture techniques are fundamental to biomedical research, providing crucial insights into cellular functions, drug discovery, and disease mechanisms. A critical step in cell culture is the p

The antigen tells a CD4 T cell to respond; the cytokine tells it what kind of response to make. A naive CD4⁺ T cell leaving the thymus is uncommitted. Within about seventy-two hours of engaging TCR/C

Cell Signalling · Growth FactorsGrowth Factors: Families, Receptors and Signalling PathwaysGrowth factors are secreted proteins that instruct cells whether to divide, differentiate, migrate or survive

Regulatory T cells cannot make the cytokine they depend on. FOXP3 represses the Il2 locus, so every Treg lives on IL-2 secreted by the conventional T cells it exists to restrain. That asymmetry expla

Almost any inflammatory phenotype in a mouse can be assigned to a cytokine by taking that cytokine away. Neutralisation is the most direct causal test immunology has: inject a functional-grade antibo
