      eLife Assessment

      This study provides valuable insights into how HIV-1 Env modulates the nanoscale organization and dynamics of the CXCR4 co-receptor on T cells, using quantitative imaging and functional approaches, the authors present convincing evidence that gp120 engagement promotes CD4-dependent clustering and altered mobility of CXCR4, distinct from the effects of the natural ligand CXCL12. Some concerns were raised regarding the interpretation of the single-particle tracking analyses, and additional clarification or analysis may help strengthen the conclusions. The physiological relevance of the findings could be further enhanced by validation with infectious virus and by more clearly integrating the CXCR4R334X mutant observations into the central mechanistic narrative. The work will be of interest to researchers studying HIV entry and membrane receptor organization.
