Investigation of PDCD1 Gene Polymorphisms and Haplotypes in COVID‐19 Severity and Outcome in a Brazilian Population
COVID‐19 severity and survival are influenced by the host immune response to SARS‐CoV‐2. Programmed cell death 1 (PD‐1), a key immune checkpoint, regulates T‐cell activation and antiviral immune balance. Since genetic variability can modulate these responses, we investigated whether the PDCD1 polymorphisms rs11568821 C...
