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...
Role of Hematopoietic Growth Factors01:28

Role of Hematopoietic Growth Factors

Hematopoietic growth factors are molecules that regulate the differentiation rate of hematopoietic stem cells (HSCs). Erythropoietin (EPO), primarily produced by the kidneys, plays a crucial role in erythrocyte production. When oxygen levels in the blood are low, EPO is released into the bloodstream, reaching the bone marrow, where it stimulates HSCs to differentiate and mature into erythrocytes, which are vital for oxygen transport.
Thrombopoietin (TPO), mainly released by the liver,...
NF-κB-dependent Signaling Pathway02:26

NF-κB-dependent Signaling Pathway

The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

Rheumatic Heart Disease I: Introduction01:23

Rheumatic Heart Disease I: Introduction

Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...
Neurogenesis and Regeneration of Nervous Tissue01:15

Neurogenesis and Regeneration of Nervous Tissue

In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...
Small GTPases - Ras and Rho01:24

Small GTPases - Ras and Rho

Ras and Rho are small monomeric GTPases that act downstream of receptor tyrosine kinase (RTK) and regulate various cellular processes. These GTPases switch between active and inactive states by binding to guanine nucleotides.
Three regulatory proteins control their activity:

Area of Science:

  • Neuroimmunology
  • Rheumatology
  • Molecular Biology

Background:

  • The nervous system influences immune responses in autoimmune conditions via neurogenic inflammation.
  • Nerve growth factor (NGF) is crucial for neuronal survival and growth, and also modulates immune responses.
  • Evidence suggests NGF is a significant mediator in various immune and rheumatic diseases.

Purpose of the Study:

  • To review the role of nerve growth factor (NGF) in rheumatic diseases.
  • To explore potential therapeutic interventions targeting NGF in these conditions.

Main Methods:

  • Conducted a comprehensive database search (Medline, Medpilot) for articles on NGF and rheumatic conditions.
  • Included clinical trials, human specimen studies, and relevant animal model studies.
  • Analyzed 800 abstracts for relevance and content.

Main Results:

  • Nerve growth factor (NGF) is overexpressed in numerous inflammatory and degenerative rheumatic diseases.
  • NGF concentrations correlate with disease activity and inflammation extent in many conditions.
  • Significantly higher NGF levels were observed in rheumatoid arthritis compared to osteoarthritis.

Conclusions:

  • Nerve growth factor (NGF) is a critical mediator and modulator of inflammation in rheumatic diseases.
  • NGF exhibits both detrimental and regenerative effects, suggesting complex roles.
  • Therapeutic strategies involving NGF antagonists or recombinant NGF show potential.
