Relationship Between Acinetobacter baumannii Pneumonia and Human CTLA4 Gene Polymorphism (rs231775) in Relation to IL-7 Serum Levels: A Study on Host–Pathogen Dynamics

Individuals with genotypes AA and AG are characterized by protective attributes against infection with <i>Acinetobacter baumannii</i>, while those having the genotype GG are more prone to infection with this bacterium. Furthermore, an association between specific genotypes and serum levels of IL-7 can hint at the possible role of genetic polymorphism in modulating immune response in relation to bacterial infection.
