Inflammatory Response01:28

Inflammatory Response

19.2K
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,...

T Cell Types and Functions01:24

T Cell Types and Functions

3.3K
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...

Regulation of Hematopoietic Stem Cells

4.4K
All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...

Receptor Downregulation in MVBs01:15

Receptor Downregulation in MVBs

3.0K
Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that  lead to cell proliferation, migration, and differentiation. Overexpression of EGFR  stimulates cells to proliferate. Excessive  EGFR...

T Cell Activation and Clonal Selection01:22

T Cell Activation and Clonal Selection

17.5K
T cells are integral to our adaptive immune system, recognizing and effectively responding to foreign antigens. T cell activation and clonal selection are pivotal in orchestrating this immune response. This article elucidates these mechanisms, detailing the roles of cluster of differentiation (CD) markers, major histocompatibility complex (MHC) molecules, costimulatory signals, and the process of clonal selection.
Naive T cells that have not yet encountered an antigen express two primary CD...

Area of Science:

  • Immunology
  • Dermatology
  • Cell Biology

Background:

  • Dendritic cells (DCs) are crucial antigen-presenting cells bridging innate and adaptive immunity.
  • In the skin, DCs act as sentinels during immune surveillance.
  • Inflammatory cytokines significantly impact DC activation and maturation in pathological skin conditions.

Purpose of the Study:

  • To review critical differences in human DC subtypes during inflammation versus steady state.
  • To highlight the functional characteristics of human DC subsets in inflamed skin environments.
  • To explore the role of DCs in skin diseases such as psoriasis and atopic dermatitis.

Main Methods:

  • Literature review focusing on human DC subtypes.
  • Analysis of DC function in steady-state and inflammatory skin conditions.
  • Examination of DC roles in specific inflammatory skin diseases.

Main Results:

  • Significant differences exist in human DC subtypes between inflammatory and steady-state conditions.
  • Specific DC subsets exhibit distinct functional characteristics in inflamed skin.
  • DC subsets play complex immunoregulatory roles in psoriasis and atopic dermatitis.

Conclusions:

  • Understanding distinct DC subset functions in inflamed skin is vital.
  • This knowledge is key for developing novel anti-inflammatory therapies for skin diseases.
