Unveiling the molecular activity of HIV towards the CD4: A study based on subtype C via docking and dynamics approach.
Article in Journal, genetic engineering & biotechnology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAcquired Immunodeficiency Syndrome (AIDS) is a critical global health issue caused by the human immunodeficiency virus (HIV). It has different strains and subtypes; among these, Subtype C accounts for higher infection rates than others. Despite its high prevalence, the molecular interactions with host receptors, specifically CD4, have not yet been explored.
methodsThis study investigates the molecular interactions between HIV subtype C and the CD4 receptor via docking and dynamics approach. Four HIV targets were examined, and their structure was modelled. Subsequently, these models were docked with the CD4 to analyze their binding interaction. The stability was examined over 200 simulations via Desmond software, and trajectories were analyzed, followed by Root mean square deviation (RMSD), root mean square fluctuation (RMSF), and the radius of gyration (Rg), PCA (principal component analysis), etc., to assess their stability and interaction dynamics.
resultsThe four target structures were modelled, and their quality was validated. Further, the docking analysis with CD4 revealed that the Envelope glycoprotein has -13.6 kcal/mol, protease has -11.2 kcal/mol, Reverse transcriptase has -12.4 kcal/mol, and integrase has -13.1 kcal/mol binding affinity towards it, followed by the number of hydrogen bond, such as 9, 6, 11, 6. The simulation over 200 ns demonstrated that the average RMSD for each complex started stabilizing within the 0.9 Å - 3.4 Å, followed by 25-50 ns, whereas the RMSF, Rg and PCA revealed the relative compactness and flexibility varied across different viral targets.
conclusionsThe study successfully identified the interactive residues of HIV subtype C toward the CD4 receptor. The binding affinities and stability data provide valuable insights into Subtype C's molecular interactions with the host, and these findings underscore the potential for developing treatments that disrupt these interactions to combat HIV more effectively.
