Summary
Phosphoinositide 3-kinases (PI3Ks), particularly the p110delta isoform, are crucial for immune cell function. This review details their vital roles in T-cell development and immunity.
Area of Science:
- Immunology
- Cell Biology
- Molecular Biology
Background:
- Phosphoinositide 3-kinases (PI3Ks) are key regulators of cellular processes.
- The p110delta isoform of PI3K is predominantly expressed in immune cells.
- PI3Ks influence metabolism, growth, gene expression, and cell migration.
Purpose of the Study:
- To review the critical roles of PI3Ks in T-cell development.
- To elucidate the function of PI3K isoforms in immune cell regulation.
- To highlight the significance of p110delta in T-cell immunity.
Main Methods:
- Literature review of PI3K research in T-cell biology.
- Analysis of studies on PI3K isoform function in immune cells.
- Synthesis of data on T-cell development and differentiation pathways.
Main Results:
- PI3K p110delta and p110gamma have complementary roles in thymic T-cell development.
- p110delta isoform regulates differentiation of peripheral helper T-cells (Th1 and Th2).
- p110delta is essential for the proper function of regulatory T-cells (Tregs).
Conclusions:
- PI3Ks, especially p110delta, are indispensable for T-cell development and function.
- Dysregulation of PI3K signaling can impact cellular and humoral immunity.
- Understanding PI3K roles offers insights into immune system regulation and potential therapeutic targets.

01:22T 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.

01:22PI3K/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...
