Antigens Involved in Adaptive Immunity

Antigens Involved in Adaptive Immunity

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.

Complete antigens possess both immunogenicity and reactivity.

Antigen Processing Pathways

Antigen Processing Pathways

MHC molecules are key players in the immune response, enabling T cells to recognize and respond to specific antigens. They are present on the surface of all nucleated cells in the body and are instrumental in presenting antigens to T cells and activating them. T cells recognize the MHC-antigen complex and initiate an immune response. MHC class I and MHC class II are two main types of MHC molecules, each associated with a distinct antigen processing pathway.
MHC Class I: Presenting Endogenous...

Renewal of Intestinal Stem Cells

Renewal of Intestinal Stem Cells

The intestinal epithelial lining rapidly renews every 4 to 5 days. The renewal is facilitated by intestinal stem cells (ISCs) located at the base of the crypt– a gland located at the bottom of each villus. ISCs divide asymmetrically to form new stem cells and progenitor daughter cells. The daughter cells are called transit-amplifying (TA) cells which move upwards along the crypt and either differentiate into absorptive cells– the enterocytes or secretory cells– including the goblet,...

Absorption of Nutrients

Absorption of Nutrients

Absorption refers to taking dietary nutrients from the intestinal lumen for transportation throughout the body. After digestion in the small intestine, carbohydrates, proteins, and fats are broken down into simpler forms. These essential macronutrients and other vital substances, such as vitamins, minerals, and water, are then prepared for absorption into the bloodstream.
Enterocytes, which are specialized polar epithelial cells, line the mucosa of the small intestinal walls. These cells...

Summary

This summary is machine-generated.

Developing oral vaccines is challenging, but understanding how M cells in the small intestine take up antigens is key. Identifying the signaling pathways involved can help create more effective gut-associated lymphoid tissue targeted vaccines.

Immunology

Background:

Oral vaccine delivery offers advantages over injections but faces challenges.
The small intestine's M cells within gut-associated lymphoid tissues are crucial for immune responses to oral antigens.
Mechanisms of M cell antigen uptake and signaling are not fully understood.

Purpose of the Study:

To explore the signaling pathways involved in M cell antigen uptake.
To identify specific pattern recognition receptors (PRRs) crucial for M cell transcytosis.
To inform the design of novel oral vaccines targeting gut-associated lymphoid tissue.

Main Methods:

Review of current research on M cell biology and antigen recognition.
Analysis of pattern recognition receptors (PRRs) involved in M cell function.
Investigation of signaling pathways initiated by receptor-ligand interactions on M cells and enterocytes.

Main Results:

Several PRRs, including toll-like receptor-4, platelet-activating factor receptor, and alpha5beta1 integrin, are implicated in M cell antigen transcytosis.
These PRRs are also present on neighboring enterocytes, suggesting differential signaling.
Specific signaling mechanisms initiating antigen uptake remain largely unknown.

Conclusions:

Understanding PRR-mediated signaling in M cells is critical for oral vaccine development.
Targeting these pathways could enhance the efficacy of oral vaccines delivered to the gut-associated lymphoid tissue.
Further research into signaling transduction pathways is needed for effective oral vaccine design.
