Summary
Host immunity combats COVID-19. This review details how single-cell studies reveal immune cell changes during SARS-CoV-2 infection and vaccination, aiding targeted therapies.
Area of Science:
- Immunology and Virology
- Genomics and Bioinformatics
Background:
- Host immune responses are critical for combating COVID-19.
- Single-cell transcriptomics offers high-resolution insights into cellular and molecular mechanisms of immunity against SARS-CoV-2.
- Understanding immune cell dynamics is crucial for developing effective COVID-19 treatments.
Purpose of the Study:
- To systematically review single-cell transcriptomic studies on host immune responses to SARS-CoV-2 infection and vaccination.
- To describe virus-induced dysregulation in immune cell abundance and molecular behavior.
- To identify specific immune cell populations associated with COVID-19 for therapeutic targeting.
Main Methods:
- Systematic review of single-cell transcriptomic studies published in the last 3-4 years.
- Analysis of immune cell types and states in COVID-19 patients and vaccinated individuals.
- Characterization of cellular and molecular changes in innate and adaptive immunity.
Main Results:
- Detailed description of SARS-CoV-2-induced alterations in immune cell populations and states.
- Insights into the molecular behavior of immune cells during infection and post-vaccination.
- Identification of specific dysregulated immune cell subsets relevant to COVID-19 pathogenesis.
Conclusions:
- Single-cell transcriptomics provides a high-resolution view of immune dysregulation in COVID-19.

Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...

The T and B lymphocytes of the adaptive immune system develop from common lymphoid progenitor cells in the bone marrow. These progenitors give rise to precursors that eventually develop into both T and B lymphocytes. As these precursors mature, they gain the ability to detect and respond to foreign antigens in the body, a process known as immunocompetence. Additionally, these precursors acquire self-tolerance, a process that ensures they do not react to self-antigens. This intricate system...
