Antigen Processing Pathways01:31

Antigen Processing Pathways

1.9K
MHC molecules are key players in the immune response, enabling T cells to recognize and respond to specific antigens. They are present on the surface of all nucleated cells in the body and are instrumental in presenting antigens to T cells and activating them. T cells recognize the MHC-antigen complex and initiate an immune response. MHC class I and MHC class II are two main types of MHC molecules, each associated with a distinct antigen processing pathway.

The Antiviral System of Bacteria and Archaea: CRISPR01:23

The Antiviral System of Bacteria and Archaea: CRISPR

486
CRISPR stands for Clustered Regularly Interspaced Short Palindromic Repeats is a adaptive immune system found in bacteria and archaea that protects against viral infections. This system enables prokaryotic cells to identify, remember, and neutralize foreign genetic elements, primarily bacteriophages, by storing fragments of the invader’s DNA as a genetic memory.The CRISPR immune response begins during an initial infection. Cas (CRISPR-associated) proteins play a central role in this...

Viruses of Archaea01:29

Viruses of Archaea

339
Archaeal viruses play a crucial role in the ecosystems of extremophilic archaea, particularly those belonging to the phyla Euryarchaeota and Crenarchaeota. By shaping host evolution and facilitating gene transfer, these viruses influence microbial communities and contribute to genetic diversity in extreme environments. The archaea they infect thrive in acidic hot springs and hydrothermal vents characterized by high temperatures and low pH. Archaeal viruses exhibit remarkable structural...

Hybridoma Technology01:31

Hybridoma Technology

16.7K
Hybridoma technology is used for the large-scale production of monoclonal antibodies. Monoclonal antibodies bind to only a single antigenic determinant or epitope. Such antibodies are used in research, diagnostics, and disease therapy. The hybridoma technology established in 1975 by Georges Köhler and Cesar Milstein was awarded the Nobel Prize in Medicine in 1984 for revolutionizing research and therapy.

Viruses with RNA Genomes01:29

Viruses with RNA Genomes

515
RNA viruses are categorized into positive-strand, negative-strand, or double-stranded groups based on their genomic structure and replication mechanisms. This classification dictates how they exploit host cellular machinery for protein synthesis and replication. Some RNA viruses also utilize reverse transcription as part of their life cycle, further diversifying their replication strategies.Positive-Strand RNA VirusesPositive-strand RNA viruses have genomes that function directly as messenger...

Area of Science:

  • Bioinformatics
  • Immunology
  • Computational Biology

Background:

  • Protein sequence analysis is key for predicting protein characteristics.
  • Current bioinformatics tools cannot directly predict if a protein will elicit a protective immune response.
  • Identifying immunogenic pathogen proteins is crucial for vaccine development.

Purpose of the Study:

  • To present Vacceed, a computational pipeline for predicting immunogenic pathogen proteins.
  • To describe the configuration and operation of Vacceed for eukaryotic pathogens.

  • Vacceed integrates multiple standalone bioinformatics programs to predict protein characteristics (e.g., secretion, membrane association).
  • Machine learning algorithms are employed to predict the likelihood of a protein inducing an immune response based on these characteristics.
  • The pipeline is designed for user-friendly operation with eukaryotic pathogens.

Main Results:

  • The study demonstrates the feasibility of predicting immunogenic proteins by combining predicted protein characteristics.
  • Vacceed provides a systematic approach to leverage computational predictions for vaccine target identification.
