Diversity of Antigen Receptors

Diversity of Antigen Receptors

Antigen receptors are essential components of the immune system crucial in defending the body against foreign invaders. These receptors are present on the surface of B and T cells, enabling them to recognize antigens and mount an appropriate immune response.
Before encountering any antigen, lymphocytes express these receptors. On B cells, the antigen receptor is a membrane-bound antibody molecule called BCR; on T cells, it is a T cell receptor or TCR. B and T cell receptors are composed of two...

Diversity in Cell Signaling Responses

Diversity in Cell Signaling Responses

The physiological function of a cell and cellular communication are outcomes of a range of extrinsic signals, intracellular signaling pathways, and cellular responses. No two cell types express the same repertoire of signaling components. Receptors are highly selective for their cognate ligands, but once activated, they can alter multiple cellular processes such as DNA transcription, protein synthesis, and metabolic activity.
Graded and Abrupt Responses
Some signaling systems generate...

Immunoglobulin-like Cell Adhesion Molecules

Immunoglobulin-like Cell Adhesion Molecules

Immunoglobulin-like cell adhesion molecules or Ig-CAMs are a versatile group of cell surface glycoproteins belonging to the immunoglobulin protein superfamily. Ig-CAMs possess the characteristic immunoglobulin protein domains and other domains such as the fibronectin type III domain. The Ig domains are glycosylated to varying degrees in different Ig-CAMs.
Ig-CAMs exhibit either homophilic binding (to other Ig-CAMs) or heterophilic binding (to other ligands such as integrins). While most Ig-CAMs...

Overview of Synapses

Overview of Synapses

A synapse is a specialized structure where two neurons connect, allowing them to pass an electrical or chemical signal to another neuron. It is the point of communication between neurons. The term "synapse" is derived from the Greek word "synapsis," which means "conjunction." The entire process of neural communication revolves around the synapse. When activated, a neuron releases chemicals known as neurotransmitters into the synapse. These neurotransmitters cross the synapse and bind to...

The Synapse

The Synapse

Neurons communicate with one another by passing on their electrical signals to other neurons. A synapse is the location where two neurons meet to exchange signals. At the synapse, the neuron that sends the signal is called the presynaptic cell, while the neuron that receives the message is called the postsynaptic cell. Note that most neurons can be both presynaptic and postsynaptic, as they both transmit and receive information.

Electrical Synapses

Electrical Synapses

Electrical synapses found in all nervous systems play important and unique roles. In these synapses, the presynaptic and postsynaptic membranes are very close together (3.5 nm) and are actually physically connected by channel proteins forming gap junctions.
Gap junctions allow the current to pass directly from one cell to the next. In contrast, in the chemical synapse, the neurotransmitters carry the information through the synaptic cleft from one neuron to the next. They consist of two...

Area of Science:

Immunology
Cell Biology
Biochemistry

Background:

Immunological synapses (ISs) form at the T cell-APC interface, crucial for T cell activation and effector functions.
Classical ISs feature a central T-cell receptor (TCR)-peptide major histocompatibility complex (pMHC) cluster surrounded by adhesion molecules.
Non-classical IS structures, including multifocal ISs and kinapses, have been observed but are less understood.

Purpose of the Study:

To review the conditions promoting the formation of non-classical ISs.
To investigate the impact of T cell and APC phenotypes on IS structure.
To discuss the functional implications of diverse IS structures in T cell activity.

Main Methods:

Literature review of existing studies on IS formation and structure.
Analysis of factors influencing IS morphology, including cell phenotypes.
Correlation of IS structural variations with T cell functional outcomes.

Main Results:

Non-classical IS formation is influenced by specific T cell and APC phenotypes.
Variations in IS structure, such as multifocal or kinapse forms, are associated with distinct cellular conditions.
IS structure plays a significant role in modulating T cell activation and effector functions.

Conclusions:

The phenotype of interacting T cells and APCs critically determines IS structure, leading to diverse non-classical forms.
Understanding these non-classical ISs provides insights into the plasticity of immune cell interactions.
IS structural diversity is a key determinant of T cell-mediated immune responses.
