Question 1

What is the Meaning of Immunopeptidome?

Accepted Answer

The immunopeptidome represents the complete collection of peptides presented on the surface of cells by Major Histocompatibility Complex (MHC) molecules, recognized by T lymphocytes. These small protein fragments originate from the breakdown of both self-proteins and foreign antigens, serving as molecular flags for immune surveillance, dynamically reflecting cellular state.

Question 2

What is the Context of Immunopeptidome?

Accepted Answer

This crucial set of peptides functions within the adaptive immune system, specifically at the interface of antigen-presenting cells and T cells. It is central to how the body differentiates healthy self-tissue from infected or abnormal cells. The precise composition guides T-cell activation, shaping the specificity of the cellular immune response.

Question 3

What is the Significance of Immunopeptidome?

Accepted Answer

Understanding the immunopeptidome holds substantial importance in clinical practice, directly influencing the body's capacity to mount effective immune responses against pathogens and malignant cells. Aberrations in this peptide display contribute to autoimmune disorders or immune evasion by tumors and viruses. Its analysis provides critical insights for therapeutic development.

Question 4

What is the Mechanism of Immunopeptidome?

Accepted Answer

Cellular proteins are continuously degraded into smaller peptides by proteasomes or other proteases. These peptides are transported into the endoplasmic reticulum, where they bind to newly synthesized MHC class I or class II molecules. The peptide-MHC complexes then traffic to the cell surface, becoming available for recognition by T-cell receptors, initiating specific immune cascades.

Question 5

What is the Application of Immunopeptidome?

Accepted Answer

The practical application of immunopeptidome analysis is increasingly evident in precision medicine, particularly for personalized cancer vaccines and immunotherapies. By identifying unique tumor-specific peptides, clinicians can design targeted interventions that direct the patient's immune system to selectively destroy cancerous tissue. It also aids in diagnosing autoimmune conditions.

Question 6

What is the Metric of Immunopeptidome?

Accepted Answer

The immunopeptidome's composition is primarily measured using advanced mass spectrometry techniques, coupled with liquid chromatography, to isolate and identify peptides bound to MHC molecules. Bioinformatic algorithms interpret these datasets to predict T-cell epitopes. Functional assays, such as T-cell activation or cytokine release assays, assess the biological relevance of identified peptides.

Question 7

What is the Risk of Immunopeptidome?

Accepted Answer

Dysregulation or misinterpretation of the immunopeptidome presents notable clinical risks. Inappropriate presentation of self-peptides can lead to severe autoimmune reactions. Conversely, failure to present critical foreign or tumor-associated antigens can result in immune tolerance, allowing infections or cancers to progress unchecked. Interventions require rigorous validation to avoid off-target effects.
