PhronesisHuman immunodeficiency virus (HIV) infection is the paradigm case of biological displacement irreversibility: a virus whose primary molecular act --- integration of viral DNA into the host genome --- produces a displacement that is structurally inaccessible to any biological return mechanism within the infected host. We present a comprehensive unit on HIV and acquired immunodeficiency syndrome (AIDS) through the displacement framework, tracing the disease from virological mechanism through the three stages of infection, the molecular basis of the latent reservoir, gut-associated lymphoid tissue (GALT) depletion, CD4-stratified immunological collapse, selenium and glutathione (GSH) depletion, antiretroviral therapy (ART) as partial displacement reduction, and the cure problem as DC5 stated biologically with full force.
The total HIV displacement cost is formalized as, where is irreducible by any currently available intervention: the latent reservoir, with a half-life of approximately 44 years, is the displacement written permanently into the genomes of resting memory CD4 T cells that will outlive any treatment course. ART reduces but leaves intact. The cure problem is not a cost problem but a structural access problem: no biological tool available to the host immune system can reach every latently infected cell or excise every integrated provirus.
Prevention, formalized as prevention of the initial integration event, is structurally superior to treatment by DC5: the latent reservoir cannot form if integration is prevented.
