T Cell Activation and Clonal Selection01:22

T Cell Activation and Clonal Selection

13.6K
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.

T Cell Types and Functions

1.7K
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.
Th1 cells stimulate dendritic cells to express necessary co-stimulatory molecules on their surfaces for...

Forced Transdifferentiation01:28

Forced Transdifferentiation

2.1K
Transdifferentiation, also known as lineage reprogramming, was first discovered by Selman and Kafatos in 1974 in silkmoths. They observed that the moths’ cuticle-producing cells transformed into salt-producing cells. Many such cases of natural transdifferentiation occur in organisms. In humans, pancreatic alpha cells can become beta cells. In newts, the loss of the eye’s lens causes the pigmented epithelial cells to transdifferentiate into the lens cells.

Area of Science:

  • Immunology
  • Cell Biology

Background:

  • CD4+ T helper (TH) cells are crucial for adaptive immunity, with distinct subsets (TH1, TH2, TH17, TH22) mediating different effector functions.
  • Systemic homeostasis and peripheral tolerance rely on a balance between effector TH cells and regulatory CD4+ T cells, including Foxp3+ regulatory T cells (Foxp3+TREG) and TR1 cells.

Purpose of the Study:

  • To establish reliable in vitro differentiation protocols for generating specific CD4+ T cell subsets from murine naïve CD4+ T cells.
  • To provide a method for obtaining both effector (TH1, TH2, TH17, TH22) and regulatory (Foxp3+TREG, TR1) T cell populations for further immunological research.

Main Methods:

  • Isolation of naïve CD4+ T cells from murine spleens.
  • Culture of isolated cells under specific cytokine and antibody conditions to induce differentiation into distinct T helper and regulatory T cell subsets.

Main Results:

  • Successful in vitro differentiation of murine naïve CD4+ T cells into TH1, TH2, TH17, and TH22 effector subsets.
  • Successful in vitro differentiation of murine naïve CD4+ T cells into Foxp3+TREG and TR1 regulatory cell subsets.

Conclusions:

  • The described protocols enable the generation of diverse CD4+ T cell subsets in vitro.
  • These methods facilitate the study of T cell subset functions and their roles in immune regulation and homeostasis.
