Glycoimmunology is an emerging field focused on understanding how immune responses are mediated by glycans carbohydrates and their interaction with glycan-binding proteins called lectins. How glycans influence immunological functions is increasingly well understood.
In a parallel way, in the HIV field, it is increasingly understood how the host immune system controls HIV persistence and immunopathogenesis. However, what has mostly been overlooked, despite its potential for therapeutic applications, is the role that the host glycosylation machinery plays in modulating the persistence and immunopathogenesis of HIV.

Here, we will survey four areas in which the links between glycan-lectin interactions and immunology, and between immunology and HIV are well described. Recent studies show that the human glycome the repertoire of human glycan structures plays critical roles in driving or modulating several cellular processes and immunological functions that are central to maintaining HIV infection.
Understanding the links between glycoimmunology and HIV infection may create a new paradigm for discovering novel glycan-based therapies that can lead to eradication, functional cure, or improved tolerance of lifelong infection.

These latently-infected cells are the source of viral rebound after interruption of antiretroviral therapy ART , and their continual reactivation in vivo probably contributes, among other drivers, to the immune activation, chronic inflammation, and organ damage that persist despite long-term suppressive therapy [ 2 , 3 ].
