T Cell Types and Functions01:24

T Cell Types and Functions

1.0K
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...

B Cell Activation and Differentiation

1.7K
The adaptive immune response, a sophisticated defense mechanism, relies on the activation and differentiation of B lymphocytes, or B cells. These processes enable our bodies to mount a tailored response against specific pathogens such as bacteria, free virus particles, toxins, and parasites.
When naive B cells encounter a specific antigen that can bind to the B cell receptor (BCR) on their surface, they undergo sensitization to respond to the antigen's presence. Sensitization begins with...

T Cell Activation and Clonal Selection

706
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.
Naive T cells that have not yet encountered an antigen express two primary CD...

Diversity of Antigen Receptors

Antigen receptors are essential components of the immune system crucial in defending the body against foreign invaders. These receptors are present on the surface of B and T cells, enabling them to recognize antigens and mount an appropriate immune response.
Before encountering any antigen, lymphocytes express these receptors. On B cells, the antigen receptor is a membrane-bound antibody molecule called BCR; on T cells, it is a T cell receptor or TCR. B and T cell receptors are composed of two...

  • Inflammation

Background:

  • Atherosclerosis is a chronic inflammatory condition where the adaptive immune system plays a key role.
  • The functions of T cells and B cells in atherosclerosis are known, but their interactions are less understood.
  • These T-cell/B-cell interactions can have both protective and harmful effects on the disease process.

Purpose of the Study:

  • To review the bidirectional interactions between T cells and B cells in atherosclerosis.
  • To explore the atheroprotective and proatherogenic roles of these cellular communications.
  • To discuss the potential of targeting T-cell/B-cell interactions for therapeutic interventions in atherosclerosis.

Main Methods:

  • Literature review focusing on T-cell/B-cell interactions in atherosclerosis.
  • Analysis of existing research on adaptive immunity in cardiovascular disease.
  • Synthesis of findings regarding the dual roles of immune cell crosstalk.

Main Results:

  • T-cell/B-cell interactions are critical modulators of atherosclerosis.

  • Specific communication pathways between T and B cells dictate their functional outcomes.

Conclusions:

  • Targeting T-cell/B-cell interactions represents a promising therapeutic avenue for atherosclerosis.
  • Modulating the adaptive immune response via these cellular dialogues could offer novel treatment strategies.
  • Further research into the mechanisms of T-cell/B-cell crosstalk is warranted for clinical application.
