T Cell Types and Functions01:24

T Cell Types and Functions

830
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...

Phagocytosis of Apoptotic Cells01:17

Phagocytosis of Apoptotic Cells

3.4K
Cells undergoing apoptosis form apoptotic bodies that must be removed immediately to prevent inflammation, autoimmune diseases, and necrosis. Phagocytosis is carried out by professional phagocytes such as macrophages or  immature dendritic cells. Non-professional phagocytes such as  epithelial cells and fibroblasts also take part in this process; however, they are not as effective as professional phagocytes. 
Normal cells contain receptors that prevent them from being recognized...

The Extrinsic Apoptotic Pathway01:17

The Extrinsic Apoptotic Pathway

5.9K
The extrinsic apoptotic pathway is initiated when extracellular death-inducing signals, such as specific cytokines, activate the death receptors expressed on the cell surface. The immune cells involved in this pathway are natural killer cells (NK cells) and cytotoxic T-lymphocytes. NK cells are critical in innate immune response, while cytotoxic T-lymphocytes are associated with adaptive immune response. These cells recognize specific receptors expressed on the altered cells and activate...

The Intrinsic Apoptotic Pathway01:31

The Intrinsic Apoptotic Pathway

6.0K
Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...

The JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

8.6K
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as  SH2...

Cytotoxic T Cells-mediated Immune Response01:27

Cytotoxic T Cells-mediated Immune Response

826
Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...

Area of Science:

  • Immunology
  • Pathology
  • Cell Biology

Background:

  • Rheumatoid arthritis (RA) is a chronic, systemic autoimmune disease.
  • RA involves synovial inflammation, pannus formation, and joint destruction.
  • Programmed cell death (PCD) is implicated in RA pathogenesis.

Purpose of the Study:

  • To review studies linking PCD and RA.
  • To deepen understanding of RA pathogenesis.
  • To guide clinical management of RA.

Main Methods:

  • Literature review of relevant studies.
  • Analysis of PCD mechanisms in RA.
  • Synthesis of current research findings.

Main Results:

  • PCD, including apoptosis, autophagy, pyroptosis, necroptosis, and ferroptosis, plays a key role in RA.
  • Imbalances in PCD lead to inflammatory factor release.
  • This exacerbates synovial inflammation and joint damage in RA.

Conclusions:

  • PCD dysregulation is central to RA pathogenesis.
  • Further research into PCD is needed for RA insights.
  • Targeting PCD may offer new therapeutic strategies for RA.
