T Cell Types and Functions01:24

T Cell Types and Functions

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...
Antiprotozoal Agents01:21

Antiprotozoal Agents

Leishmaniasis is a widespread parasitic disease caused by several Leishmania species. It affects millions of people each year and remains a major public health problem in endemic regions. First-line treatment relies on pentavalent antimonials, including meglumine antimoniate and sodium stibogluconate. Even so, how these drugs work has not been fully clear, especially their interaction with parasite-specific biochemical pathways. One key target is trypanothione reductase (TR), an enzyme that...

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF

Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab (Humira),...

Area of Science:

  • Endocrinology
  • Immunology
  • Rheumatology

Background:

  • Leptin, secreted by adipocytes, regulates metabolism and energy homeostasis.
  • Leptin structurally resembles proinflammatory cytokines, suggesting a role in immune regulation.
  • Altered leptin levels are linked to infection susceptibility and autoimmune disorders.

Purpose of the Study:

  • To review recent advances in understanding leptin's role in immune-rheumatological diseases.
  • To explore the therapeutic potential of modulating leptin levels for autoimmune disorders.

Main Methods:

  • Review of in vitro and clinical studies on leptin's immune functions.
  • Analysis of the relationship between leptin, nutritional status, and immune competence.
  • Examination of leptin's association with autoimmune and inflammatory conditions.

Main Results:

  • Reduced leptin production correlates with increased susceptibility to infections.
  • Increased leptin secretion and pro-inflammatory cytokine production are observed in autoimmune diseases.
  • Leptin's structural similarity to cytokines highlights its immune-regulatory functions.

Conclusions:

  • Leptin is a critical mediator between nutritional status and immune function.
  • Leptin modulation may offer novel therapeutic strategies for autoimmune diseases.
  • Further research into leptin's role in rheumatological conditions is warranted.
