INNATE/ADAPTIVE RESPONSE TO COVID-19
This section will focus on the innate response vs the adaptive response our body mounts in response to COVID.
Nuance
A higher concentration of innate immune response has been seen to be elucidated by COVID-19.
After sequencing Bronchoalveolar Lavage Fluid cells from the esophagi of COVID patients demonstrate higher levels of transcription of genes for cytokines and interferon stimulated genes
Neutrophils, Eosinophiles, Macrgophages, Dendritic cells account for the release of innate Cytokines.
Generally
In pediatric patients vs older, The innate response is more tame in the younger group
Acute responses, overburdening of the body by cytokines (IL-1, IL-6, IL-8, CXCL-10) have resulted in the most severe COVID cases.
Humoral and Cellular Response
-N & S specific antibody release by B cells target virus
- Viral antigen presentation causes cellular response and activation of CD8+ cytotoxic T cells and CD4+ T helper cells.
T cell recruitment - effectiveness of the adaptive pathway determines the bodies ability to ward off disease severity.
Cytokine Storm (IL-6, IL-10, and TNFα) and significantly reduced CD4+ and CD8+ T cells recruitment allows COVID to overwhelm body.
Overbearing Cytokine production from dysregulated immune response causes hyperinflammation. Marginalizes the effectiveness of antiviral agents alone as a treatment because hyperinflammation from own body's cytokine production persists.
