T Cell Types and Functions01:24

T Cell Types and Functions

990
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...

Introduction to Innate and Adaptive Immunity

3.9K
The human immune system is a complex defense mechanism that protects the body from harmful pathogens and foreign substances. It comprises two crucial components: innate and adaptive immunity.
Innate immunity is the body's natural, nonspecific defense system that acts quickly to protect against pathogens. It incorporates physical barriers like skin and mucous membranes and cellular elements such as phagocytes and natural killer cells. This part of our immune system provides an immediate,...

Inflammatory Response01:28

Inflammatory Response

1.9K
An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...

Cells of the Innate Immune Response

1.6K
The innate immune response is an immediate and non-specific response against pathogens, acting swiftly to prevent the spread of infections. The primary cells involved in this response are phagocytes and natural killer (NK) cells.
Phagocytes
Phagocytes police the peripheral tissues by removing cellular debris and responding to the invasion of foreign substances or pathogens. Many phagocytes attack and remove microorganisms even before lymphocytes detect them. The human body has two general...

Area of Science:

  • Immunology
  • Dermatology
  • Pathogenesis of skin diseases

Background:

  • Atopic dermatitis (AD) is a chronic inflammatory skin condition marked by recurring eczema and intense itching.
  • AD relapses significantly impact patients' quality of life due to economic and time burdens.

Purpose of the Study:

  • To review recent findings on the role of innate immune cells in atopic dermatitis.
  • To highlight the significance of innate immunity in AD pathogenesis and treatment.

  • Atopic dermatitis pathogenesis is multifactorial, involving genetic, barrier, immune, microbial, and environmental influences.
  • Innate immune cells are increasingly recognized for their critical involvement in AD onset and progression.

Conclusions:

  • Innate immune cells are essential players in the complex pathogenesis of atopic dermatitis.
  • Clinical treatment strategies for AD should increasingly consider the perspective of innate immunity.
