The membranous epithelial (M) cell and the mucosal immune system
Annual Review of Medicine
|January 1, 1984
Summary
Membranous epithelial (M) cells transport antigens across mucosal barriers. This review details M cell structure, function, and immune system interactions, crucial for understanding mucosal immunity and disease.
Area of Science:
- Immunology
- Cell Biology
- Gastroenterology
Background:
- Membranous epithelial (M) cells are specialized cells in the gut and respiratory tracts.
- They are located over lymphoid follicles and act as a gateway for antigens.
Purpose of the Study:
- To review the structure and function of M cells.
- To discuss their role in antigen uptake and transport.
- To explore M cell interactions with the immune system.
Main Methods:
- Literature review of M cell structure and function.
- Analysis of M cell's role in antigen transport.
- Examination of M cell interactions with immune components.
Main Results:
- M cells actively endocytose and transport antigens and microorganisms.
- This transport occurs across the mucosal barrier into Peyer's patches and lymphoid tissues.
- Antigen presentation by M cells can initiate immune responses or lead to disease.
Conclusions:
- M cells are critical for mucosal immunity surveillance.
- Understanding M cell function is key to developing strategies against mucosal pathogens.
- M cells play a dual role in initiating immunity and potentially facilitating disease spread.

13.5K
A tissue membrane is a thin layer of cells that covers the outside of the body, the organs, internal passageways that lead to the exterior of the body, and the lining of the moveable joint cavities. There are two basic types of tissue membranes— connective tissue and epithelial membranes.
Connective Tissue Membranes
The connective tissue membrane is formed solely from connective tissue. These membranes encapsulate organs, such as the kidneys, and line our movable joints. A synovial...

Lymphoid cells and tissues are integral to the immune system, which is crucial in maintaining our body's defense against harmful pathogens. They form the building blocks of lymphoid organs, which include the spleen, thymus, and lymph nodes.
Lymphoid cells consist of various types of immune system cells. These include B and T lymphocytes, which are responsible for producing antibodies and killing infected cells, respectively. Dendritic cells act as messengers between the innate and adaptive...

Secondary organs, including lymph nodes, the spleen, and mucosa-associated lymphoid tissue (MALT), work harmoniously to protect us from disease and infection.
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...

The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...

01:26Antigens Involved in Adaptive Immunity
1.7K
An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.
