Proteomics

Proteomics

A proteome is the entire set of proteins that a cell type produces. We can study proteomes using the knowledge of genomes because genes code for mRNAs, and the mRNAs encode proteins. Although mRNA analysis is a step in the right direction, not all mRNAs are translated into proteins.
Proteomics is the study of proteomes' function. It involves the large-scale systematic study of the proteome to denote the protein complement expressed by a genome. Scientist Mark Wilkins coined the term...

Immune Response Against Viral Pathogens

Immune Response Against Viral Pathogens

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...

Area of Science:

Immunology
Virology
Genomics

Background:

The COVID-19 pandemic necessitates understanding immune responses for effective management.
The immediate post-diagnosis phase of SARS-CoV-2 infection is understudied.
Identifying early immune signatures can predict disease trajectory.

Approach:

Collected blood samples from COVID-19 patients shortly after diagnosis.
Performed multi-omic analyses (transcriptomic, epigenomic) on immune cells.
Compared molecular profiles between patients with mild (Non-progressors) and severe (Progressors) disease outcomes.

Key Points:

Progressors showed higher levels of cytokines, notably IL-6.
Monocyte subsets (non-classical, intermediate) were decreased in Progressors.
CD8+ T effector memory cells exhibited enhanced activation signatures in Progressors.

Conclusions:

Early immune cell composition and molecular signatures differentiate COVID-19 disease severity.
These early changes in immune profiles can serve as prognostic biomarkers.
Findings may inform the development of targeted interventions for severe COVID-19.
