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...

Irritable Bowel Syndrome I: Introduction

271
Irritable Bowel Syndrome (IBS) is characterized by functional disturbances in the gastrointestinal system, presenting a cluster of symptoms without evident structural or biochemical abnormalities. It primarily affects the large intestine and may cause abdominal pain, bloating, excessive gas, diarrhea, constipation, or both.
IBS is a chronic condition that can persist over a long period or recur frequently.
The pathogenesis of IBS involves a complex interplay of the following factors:
Altered...

Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

445
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

The JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

8.8K
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...

Defense Against Bacterial Pathogens01:31

Defense Against Bacterial Pathogens

1.4K
The human immune system is a complex network of cells, tissues, and organs that work together to defend the body against bacterial infections. It consists of various immune cells, each playing a specific role in the defense mechanism.
Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...

Area of Science:

  • Microbiome research
  • Immunology
  • Gastroenterology

Background:

  • Growing evidence links gut dysbiosis to inflammatory arthropathies.
  • Observational studies suggest an association but face confounding factors.

Purpose of the Study:

  • To explore the complex relationship between intestinal microbiota and arthritis.
  • To evaluate the challenges in establishing causality and potential therapeutic strategies.

Main Methods:

  • Review of observational studies and animal models.
  • Analysis of interventional trials and microbiota modulation techniques.

Main Results:

  • Observational data are insufficient to establish causality due to confounders.
  • Animal models suggest mechanisms like barrier dysfunction and molecular mimicry.
  • Interventional trials are technically limited but necessary.

Conclusions:

  • The association between gut microbiota and arthritis is recognized, but causality remains unproven.
  • Therapeutic strategies targeting the microbiota show promise but require further validation.
