Recent findings suggest the HIV latent reservoir is dynamic, not static. Infected CD4+ T cells proliferate and are eliminated, impacting HIV cure strategies.
Area of Science:
- Immunology
- Virology
- Infectious Diseases
Background:
- HIV-1 cure remains a global challenge.
- Antiretroviral therapy (ART) suppresses but does not eliminate HIV.
- The latent reservoir of infected CD4+ T cells is a key barrier to HIV eradication.
Purpose of the Study:
- To review recent data on infected CD4+ T cell dynamics during ART.
- To explore implications for HIV cure strategies.
Main Methods:
- Review of current scientific literature and data.
- Analysis of evidence supporting a dynamic model of HIV persistence.
- Examination of mechanisms of infected cell expansion and elimination.
Main Results:
- Evidence suggests the latent reservoir is dynamic, not stable.
- An equilibrium exists between proliferation and elimination of HIV-infected cells.
- This dynamic nature challenges previous assumptions about reservoir stability.
Conclusions:
- The dynamic nature of the HIV reservoir has significant implications for developing effective cure strategies.
- Understanding these dynamics is crucial for future HIV eradication research.
- New therapeutic approaches may need to target this dynamic equilibrium.

Protein Dynamics in Living Cells
Fluorescent recovery after photobleaching (FRAP) is a fluorescent-protein-based detection technique used to quantify protein movement rates within the cell. This method exposes a small portion of the cell to an intense laser beam. The laser beam causes permanent photobleaching of the fluorophore-tagged proteins in the exposed region. As the bleached...

SN1 Reaction: Stereochemistry
In the first step of an SN1 reaction, the bond between the electrophilic carbon and the leaving group ionizes to generate the carbocation intermediate. The second step of the mechanism is the nucleophilic attack.
In the formed carbocation, the positively charged carbon is sp2 hybridized with a trigonal planar geometry. As all the three substituents lie on the same plane, a plane of symmetry for the...
SN1 Reaction: Kinetics
However, Sir Christopher Ingold and Edward D. Hughes, who studied the kinetics of various nucleophilic substitution reactions, noticed that a tertiary alkyl halide does undergo a nucleophilic substitution reaction in the presence of a weak nucleophile. While studying the substitution...
SN1 Reaction: Mechanism
Firstly, the haloalkane ionizes to generate a carbocation intermediate and a halide ion. This heterolytic cleavage is highly endothermic with large activation energy. The ionization of the substrate, facilitated by a...
