PI3Ks (phosphoinositide 3-kinases) regulate diverse cellular functions such as metabolism, growth, gene expression and migration. The p110delta isoform of PI3K is mainly expressed in cells of the immune system and contributes to cellular and humoral immunity. In the thymus, p110delta and p110gamma play complementary roles in regulating the transition through key developmental checkpoints. In addition, p110delta regulates the differentiation of peripheral Th (helper T-cells) towards the Th1 and Th2 lineages. Moreover, p110delta is critical for Treg (regulatory T-cell) function. Here, we review the role of PI3Ks in T-cell development and function.

T Cell Activation and Clonal Selection

T cells are integral to our adaptive immune system, recognizing and effectively responding to foreign antigens. T cell activation and clonal selection are pivotal in orchestrating this immune response. This article elucidates these mechanisms, detailing the roles of cluster of differentiation (CD) markers, major histocompatibility complex (MHC) molecules, costimulatory signals, and the process of clonal selection.

PI3K/mTOR/AKT Signaling Pathway01:22

PI3K/mTOR/AKT Signaling Pathway

The mammalian target of rapamycin  (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1  (mTORC1) and mTOR complex 2  (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast,  mTORC2 consists of a rapamycin-insensitive companion...
