Understanding the earliest immune responses following HIV infection is critical to inform future vaccines and therapeutics. Here, we review recent prospective human studies in at-risk populations that have provided insight into during acute infection, including additional relevant data from non-human primate (NHP) studies. We discuss timing, nature, function of diverse induced, onset dysfunction, effects early anti-retroviral therapy administration. Treatment at viremia mitigates peripheral T B cell limits seroconversion, enhances cellular antiviral immunity despite persistence lymphoid tissues. highlight pertinent areas for investigation, how application high-throughput technologies, alongside targeted NHP studies, may elucidate response features target novel preventions cures.

Cells of the myeloid lineage, particularly macrophages, serve as primary hosts for HIV in vivo, along with CD4 T lymphocytes. Macrophages are present virtually every tissue organism, including locations negligible cell colonization, such brain, where HIV-mediated inflammation may lead to pathological sequelae. Moreover, infected macrophages multiple other tissues. Recent evidence obtained humanized mice and macaque models highlighted capacity sustain replication vivo absence cells. Combined known resistance macrophage cytopathic effects infection, data brings a renewed interest this type both vehicle viral spread well reservoir. While our understanding key processes infection is far from complete, recent years have nevertheless brought important insight into uniqueness infection. Productive by can occur different routes phagocytosis In assembles buds peculiar plasma-membrane-connected compartment that pre-exists function remains elusive, it supposedly allows persistence infectious particles over extended periods time play role on transmission. As cells innate immune system, detect respond components. suggest sensing at steps cycle impact subsequent spread. We aim provide an overview HIV-macrophage interaction stages life cycle, extending when pertinent observations additional types dendritic or blood monocytes.

Toll-like receptors (TLRs) are a family of pattern recognition and part the first line defense against invading microbes. In humans, we know 10 different TLRs, which expressed to varying degrees in immune cell subsets. Engaging TLRs through their specific ligands leads activation innate system secondarily priming adaptive system. Because these unique properties, TLR agonists have been investigated as immunotherapy cancer treatment for many years, but recent years there has also growing interest use context human immunodeficiency virus type 1 (HIV-1) cure research. The primary obstacle curing HIV-1 is presence latent viral reservoir transcriptionally silent cells. Due very limited transcription integrated proviruses, latently infected cells cannot be targeted cleared by effector mechanisms. interesting this because potential dual effects latency reverting agents (LRAs) modulatory compounds. Here, review preclinical clinical data on impact stimulation well antiviral HIV-1-specific immunity. We focus promising role combination strategies Different combinations broadly neutralizing antibodies or adjuvants vaccines shown encouraging results non-human primate experiments concepts now moving into testing.
