HIV-1 subtype C dominates nearly half of global infections, yet its epidemiological success appears at odds with standard lab measures of viral replication fitness.
- Why it matters: Conventional assays in activated peripheral blood mononuclear cells and blood-derived macrophages may miss ecological determinants that shape success during transmission and infection in human populations.
- What they did: The work synthesizes evidence that subtype C fitness may depend on changing cellular, anatomical, immunological, and epidemiological environments, highlighting traits like persistent CCR5 usage, CpG content, LTR promoter architecture, and Tat function.
- The result: It suggests subtype C may model how adaptation to shifting host environments can shape transmission, persistence, disease progression, and viral loads, rather than implying a uniformly higher or lower fitness lineage.
