Tumor Immunotherapy

Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

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.

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs

Asthma is a chronic respiratory condition for which new therapeutic avenues, including anti-inflammatory drugs like mast cell stabilizers and anti-IgE treatments, continue to be developed.
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...

Antibody Structure

Antibody Structure

Overview
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.
The Y-Shaped Structure of Antibodies Consists of Four Polypeptide Chains
Antibodies consist of four polypeptide chains: two identical heavy...

Area of Science:

Allergy and Immunology
Immunotherapy Research
Computational Biology

Background:

Allergen-specific immunotherapy (SIT) has been used for over 100 years to treat allergies.
Ongoing research aims to enhance SIT efficacy and minimize adverse effects.
Understanding the mechanisms of SIT, including T-cell regulation and antibody class switching, is crucial.

Purpose of the Study:

To review the existing literature on peptide immunotherapy for inhaled allergens.
To evaluate the potential of T-cell epitope peptides in SIT.
To explore novel approaches for developing effective peptide-based immunotherapies.

Main Methods:

A comprehensive literature search was conducted on Medline for studies on peptide SIT for aeroallergens.
Analysis of existing research on allergen modification and treatment routes.
Review of cellular, animal, and clinical study outcomes.

Main Results:

T-cell epitope peptides, lacking IgE-binding sites, were initially promising for inducing regulatory T (Treg) cells and reducing T helper (Th)2 cells.
While cellular and animal studies showed success, clinical trials of T-cell peptide immunotherapy yielded limited efficacy and side effects.
Challenges included high placebo response rates and the development of IgE against T-cell epitopes.

Conclusions:

Hypoallergenic B cell epitope peptides represent a promising new direction for peptide immunotherapy.
Computational identification methods are vital for discovering and designing novel peptide immunotherapies.
Future strategies may involve modifying IgE-allergen binding through blocking antibodies.
