T Cell Types and Functions

2.0K
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...

Rheumatic Heart Disease I: Introduction

348
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...

Area of Science:

  • Neuroscience
  • Immunology
  • Genetics

Background:

  • Rett syndrome (RTT) is a neurodevelopmental disorder caused by mutations in the methyl-CpG-binding protein 2 (MECP2) gene.
  • RTT presents with neurological symptoms and multisystemic features, including immune dysfunction and inflammation.
  • The precise mechanisms underlying RTT pathophysiology remain unclear.

Purpose of the Study:

  • To review current knowledge on the role of inflammatory and immune responses in RTT.
  • To explore how immune system abnormalities contribute to RTT development and progression.

Main Methods:

  • Literature review of studies investigating immune and inflammatory pathways in RTT.
  • Analysis of findings related to humoral and cell-mediated immunity in RTT patients.

Main Results:

  • Dysregulated immune responses, including humoral and cell-mediated abnormalities, are characteristic of RTT.
  • Chronic low-grade inflammation is present in multiple organs in RTT.
  • These immune and inflammatory alterations may contribute to the disease's development and worsening course.

Conclusions:

  • Immune dysfunction and chronic inflammation are integral to RTT pathophysiology, not just symptoms.
  • Targeting immune dysfunction presents a potential therapeutic strategy for managing RTT.
