The class I phosphoinositide‑3‑kinases (PI3Ks) are heterodimeric enzymes that phosphorylate phosphatidyl‑inositol‑4,5‑bisphosphate (PIP₂) to generate the second messenger phosphatidyl‑inositol‑3,4,5‑trisphosphate (PIP₃). Among the four catalytic isoforms (α, β, δ, γ), and PI3Kγ are predominantly expressed in leukocytes and regulate B‑cell receptor (BCR) signaling, cytokine production, and chemotaxis. Aberrant activation of these isoforms sustains survival of chronic lymphocytic leukemia (CLL), mantle‑cell lymphoma (MCL), and contributes to the inflammatory cascade in autoimmune diseases such as ulcerative colitis (UC) and rheumatoid arthritis (RA) (Miller et al., 2021; Zhou & He, 2022).
