Autoimmune Disorders01:29

Autoimmune Disorders

2.3K
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

The Oral Microbiota01:27

The Oral Microbiota

57
The oral microbiome includes a complex ecosystem comprising over 700 microbial species, identified through genomic sequencing and culture-based analyses to date. This community includes a core microbiome, found universally among individuals, and a variable component influenced by environmental factors such as diet, lifestyle, and host genetics. Site-specific conditions, including oxygen gradients, pH levels, and nutrient availability, determine the spatial distribution of these microorganisms...

Introduction to the Human Microbiota

100
Microorganisms colonize various regions of the human body, including the mouth, nasal passages, throat, stomach, intestines, urogenital tract, and skin. The total number of microbial cells is estimated to range from 10¹³ to 10¹⁴—comparable to, or exceeding, the number of human somatic cells. This host–microbiome relationship has led to the conceptualization of humans as supraorganisms, wherein microbial communities perform vital roles in development, immunity,...

Functions of the Gut Microbiota

82
The gut microbiota includes trillions of microorganisms that colonize the human gastrointestinal tract, including bacteria, archaea, viruses, and fungi. This complex ecosystem plays a critical role in maintaining intestinal and systemic health. Most of these microbes inhabit the large intestine, establishing a relatively stable and diverse community that contributes to gut homeostasis through various metabolic, immunological, and protective mechanisms.Dominant bacterial phyla, such as...

T Cell Types and Functions

3.4K
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...

Area of Science:

  • Immunology
  • Microbiology
  • Autoimmunity

Background:

  • The commensal microbiota plays a critical role in host immune system regulation, including responses to pathogens.
  • Emerging evidence suggests the microbiota also significantly influences autoimmune responses.
  • Understanding these mechanisms is crucial for developing novel therapeutic strategies.

Purpose of the Study:

  • To discuss potential mechanisms by which the microbiota influences the development and regulation of autoimmune diseases.
  • To highlight key interaction points between the microbiota and host immune system relevant to autoimmunity.

Main Methods:

  • Review and synthesis of current literature on microbiota-host interactions in autoimmunity.
  • Discussion of immunological pathways affected by microbial communities.
  • Exploration of non-immunological mechanisms, such as hormonal interactions.

Main Results:

  • Microbiota can influence both innate and adaptive arms of the immune response.
  • Microbial effects extend to directly impacting autoimmunity targets, even during prenatal development.
  • Interactions between microbiota and host hormones are implicated in autoimmune regulation.

Conclusions:

  • The microbiota represents a significant factor in the pathogenesis and regulation of autoimmune diseases.
  • Further research into microbiota-driven mechanisms is warranted for therapeutic advancements.
  • A holistic view encompassing immunity, direct target interaction, and hormonal balance is necessary.
