Insights

Dermal dendritic cells (DDCs) in skin are not a single cell type. Research shows DDCs include immature dendritic cells and macrophages, suggesting macrophages are a novel part of the skin's innate immune response.

Area of Science:

  • Immunology
  • Dermatology
  • Cell Biology

Background:

  • The skin's immune system relies on resident dendritic cells (DCs).
  • In normal skin, DCs are found in the epidermis (Langerhans cells, LCs) and dermis (dermal DCs, DDCs).
  • The precise lineage and composition of DDCs remain incompletely understood.

Purpose of the Study:

  • To investigate the cellular lineage and phenotypic characteristics of dermal dendritic cells (DDCs).
  • To determine if DDCs represent a homogeneous or heterogeneous cell population.
  • To elucidate the role of DDCs within the resident skin immune system.

Main Methods:

  • Utilized monoclonal antibodies for cell surface marker analysis.
  • Employed immunohistology techniques to visualize cell populations within the skin.
  • Phenotypically characterized DDCs based on specific marker expression.

Main Results:

  • Evidence suggests DDCs comprise at least two distinct phenotypic populations.
  • One population exhibits markers of immature dendritic cells (CD1, CD11c, CD208).
  • A second population displays markers characteristic of macrophages (CD209, CD206, CD163, CD68).

Conclusions:

  • Dermal dendritic-appearing cells are not a single entity but include distinct macrophage populations.
  • These dermal macrophages represent a newly identified component of the innate immune response in the skin.
  • This finding redefines our understanding of the cellular composition and function of the resident skin immune system.

T Cell Activation and Clonal Selection

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.

Antigen Presenting Cells01:22

Antigen Presenting Cells

The immune system is a complex network of cells and molecules that protects the body from foreign invaders. T cells, a type of white blood cell, play a crucial role in this process. They recognize and attack foreign substances, such as pathogens, that enter the body.
T cells require the help of antigen-presenting cells (APCs), which process foreign antigens into smaller fragments that can be recognized by T cells. These APCs are highly specialized cells that efficiently internalize antigens...

Cells of the Innate Immune Response

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...

Immune Surveillance by NK Cells and Phagocytes

Immune surveillance is an integral part of the innate immune system, involving the continuous monitoring of peripheral tissues to detect and respond to pathogens, infected cells, or cancerous cells. This surveillance is conducted primarily by natural killer (NK) cells and phagocytes, which employ distinct but complementary mechanisms to identify and eliminate threats.

T Cell Types and Functions

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...
