Immune Response Against Viral Pathogens01:29

Immune Response Against Viral Pathogens

795
The immune system's response to viral infections is a complex and coordinated process involving natural killer (NK) cells, T cell-mediated responses, and antibody-mediated responses.
NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...

Antigen Processing Pathways01:31

Antigen Processing Pathways

1.0K
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.
MHC Class I: Presenting Endogenous...

Antigens Involved in Adaptive Immunity

507
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.
Complete Antigens
Complete antigens possess both immunogenicity and...

Leaky Scanning02:28

Leaky Scanning

5.1K
During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA.  Marilyn Kozak discovered that the sequence RCCAUGG (where R...

Area of Science:

  • Virology
  • Immunology
  • Bioinformatics

Background:

  • African swine fever (ASF) poses a significant threat to the global pork industry.
  • The precise mechanisms of ASFV pathogenesis and host-specific clinical variations are not fully understood.

Purpose of the Study:

  • To elucidate the comprehensive protein-protein interaction (PPI) network between ASFV and host immune pathways.
  • To explore differences in ASFV-host PPI between domestic pigs and warthogs.
  • To investigate the role of ASFV proteins in innate immune regulation via the cGAS-STING pathway.

Main Methods:

  • Deciphering the ASFV-host and ASFV-ASFV PPI network.
  • Comparative analysis of PPIs in domestic pigs versus warthogs.
  • Screening ASFV proteins for inhibitory effects on IFN-I and NF-κB signaling.

Main Results:

  • A comprehensive ASFV-host interaction landscape was established, including ASFV-host immune pathway and ASFV-ASFV PPIs.
  • Key differences in ASFV-host PPIs between domestic pigs and warthogs were identified.
  • Specific ASFV proteins interacting with the cGAS-STING pathway were found to inhibit IFN-I and NF-κB activation.

Conclusions:

  • The developed PPI network provides insights into ASFV pathology and host-specific responses.
  • Identified ASFV proteins offer potential targets for therapeutic interventions against ASF.
  • The study highlights the importance of ASFV-host PPIs in regulating innate immunity.
