Summary
Trogocytosis is a cell communication process where cells exchange membrane fragments. This immune cell interaction influences immune responses and may play a role in allergies.
Area of Science:
- Immunology
- Cell Biology
Background:
- Trogocytosis involves the transfer of membrane fragments and proteins between adjacent cells.
- This process differs from phagocytosis and cell fusion.
- It is initiated by antigen presentation or Fc receptor interaction in the immune system.
Purpose of the Study:
- To review the fundamental mechanisms of trogocytosis.
- To explore the involvement of T helper 2 (T2)-mediated immunity components in trogocytosis.
- To investigate the potential role of trogocytosis in allergic responses.
Main Methods:
- This review synthesizes existing literature on trogocytosis.
- It examines molecular mechanisms and immunological contexts.
- Focuses on T cell-mediated membrane transfer and its consequences.
Main Results:
- Trogocytosis facilitates the transfer of surface molecules like MHC, CD80, CD86, and OX-40 between immune cells.
- This transfer alters the immunological properties and modulates the activity of recipient cells.
- The process is linked to T helper 2 cell functions and potentially allergic diseases.
Conclusions:
- Trogocytosis is a significant mechanism for intercellular communication and immune modulation.
- Understanding trogocytosis offers insights into immune regulation and the pathogenesis of allergies.
- Further research into T2-mediated immunity and trogocytosis is warranted for therapeutic strategies.

133
Drug-related allergies are immune-mediated responses triggered by the administration of pharmacological agents. These hypersensitivity reactions are classified based on the immune mechanisms involved. The four primary types—Type I, II, III, and IV—are mediated by different immunological pathways and exhibit distinct clinical manifestations.Type I Hypersensitivity/ IgE-Mediated Reactions: Immunoglobulin E (IgE) immediately mediates Type I hypersensitivity reactions. Upon initial...

01:15Transcytosis of IgG
4.5K
Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...

1.6K
Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing...

The adaptive immune system, a crucial component of the overall immune response, offers a highly specialized defense against pathogens. It involves specific cell types and features, enabling it to combat infections effectively and efficiently.
The primary cell types involved in adaptive immunity are T cells and B cells. Each type has a unique role in defending the body against pathogens. T cells are responsible for cell-mediated immunity. They identify and eliminate infected cells directly,...

Hypersensitivity, also known as a hypersensitivity reaction or allergic reaction, is a condition where the body's immune system reacts abnormally to a foreign substance. Such substances, that cause hypersensitivity are referred to as an allergen, could be something typically harmless to most people, like pollen or certain foods.
Types of Hypersensitivities
