Immune Response Profiling in COVID-19 Patients
Summary
Immune response profiling in COVID-19 patients encompasses systematic analyses of both innate and adaptive components, integrating cellular, humoral and molecular measurements. Quantification of lymphocyte subsets (CD4+ and CD8+ T cells, B cells, natural killer cells), multiplex cytokine and chemokine panels, and high-resolution transcriptomic or proteomic assays have revealed characteristic patterns of lymphopaenia, hyperinflammatory cytokine release (“cytokine storm”) and T cell exhaustion. Longitudinal studies demonstrate persistent remodelling of naïve and memory T cell pools beyond acute illness, while multi-parameter signatures have identified prognostic biomarkers to stratify patient risk and guide immunomodulatory therapy. Advances in single-cell sequencing and integrated omics have illuminated mechanisms of viral pathogenesis, informed vaccine optimisation and underpinned personalised management strategies worldwide.

Immune Response Profiling in COVID-19 Patients publication trend
The graph below shows the total number of articles in immune response profiling in covid-19 patients across all publications each year (not limited to Nature Index journals).
Technical terms
CD8+ T cell: A subset of cytotoxic lymphocytes that recognise infected cells via the major histocompatibility complex and mediate targeted cell killing.
Cytokine storm: An excessive and dysregulated release of pro-inflammatory cytokines leading to systemic inflammation and tissue damage.
Naïve T cell: A mature T lymphocyte that has not yet encountered its specific antigen and circulates awaiting activation.
Lymphopaenia: A reduction in the absolute number of lymphocytes in peripheral blood, often correlating with impaired immune competence.
Biomarker: A measurable biological indicator used to predict clinical outcomes, monitor disease progression or guide therapeutic decisions.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
