Allergic Drug Reactions

1.3K
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...

Antigens Involved in Adaptive Immunity

1.2K
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.

Area of Science:

  • Food science
  • Bioinformatics
  • Immunology

Background:

  • Novel proteins from new sources and GM foods require safety assessments.
  • Allergenicity screening is vital for the safe use of these proteins.
  • Current methods rely on sequence alignment, missing conformational epitopes.

Purpose of the Study:

  • To present a protocol for predicting protein allergenicity.
  • To introduce a platform of three alignment-independent servers: AllerTOP v.1, AllerTOP v.2, and AllergenFP.
  • To offer a user-friendly, freely accessible tool for allergenicity assessment.

Main Methods:

  • Utilized three distinct alignment-independent servers (AllerTOP v.1, AllerTOP v.2, AllergenFP).
  • Employed similar datasets with varied chemical descriptors and modeling approaches.
  • Demonstrated the protocol using a stepwise approach on a query protein.

Main Results:

  • Developed a platform for allergenicity prediction independent of sequence alignment.
  • Servers utilize different methodologies for robust prediction.
  • The platform provides a user-friendly protocol for assessing novel proteins.

Conclusions:

  • Alignment-independent servers offer a complementary approach to sequence alignment for allergenicity prediction.
  • The AllerTOP and AllergenFP platform enhances the safety assessment of novel proteins.
  • This protocol facilitates faster and more reliable allergenicity screening.
