Insights
Cluster of differentiation (CD)127 expression on T cells is reduced in individuals with human immunodeficiency virus type 1 (HIV-1). Lower CD127 levels correlate with impaired CD4+ T-cell recovery and reduced naive T-cell subsets.
Area of Science:
- Immunology
- Virology
- Cell Biology
Background:
- Human immunodeficiency virus type 1 (HIV-1) infection impacts T-cell populations.
- Understanding T-cell dynamics is crucial for managing HIV-1 disease progression.
Purpose of the Study:
- To investigate cluster of differentiation (CD)127 expression in T cells of HIV-1 patients.
- To determine the relationship between CD127 expression and HIV-1 disease progression.
Main Methods:
- 139 HIV-1 patients were categorized based on CD4+ T-cell counts after highly active antiretroviral therapy (HAART).
- Flow cytometry was used to quantify T-cell subsets, including naive (CD45RA+) and memory (CD45RO+) cells, and CD127 expression.
Main Results:
- Patients with good CD4+ T-cell recovery exhibited higher counts of CD4+CD45RO+, CD4+CD45RA+, CD4+CD45RO+CD127+, and CD4+CD45RA+CD127+ T cells.
- Reduced percentages of CD45RA+ and CD127+ T cells were observed in patients with poor and general recovery.
- CD127 expression positively correlated with CD4+ T-cell counts and CD45RA+ subset percentages.
Conclusions:
- CD127 expression is diminished in T cells of HIV-1 patients.
- Decreased CD127 expression is associated with impaired CD4+ T-cell count recovery and reduced naive T-cell subsets in HIV-1 infection.
Objective:
To evaluate cluster of differentiation (CD)127 expression in T cells of patients with HIV-1 and the relationship of CD127 expression with disease progression.
Methods:
We divided 139 patients infected with human immunodeficiency virus type 1 (HIV-1) who had undergone highly active antiretroviral therapy (HAART) into 3 groups: patients with poor recovery (CD4+T < 350/μ;L, patients with general recovery (CD4+T = 350 - ∼600/μL) and patients with good recovery (CD4+T > 600/μL). Counts and percentages of naïve (CD45RA+) and memory (CD45RO+) T cells and CD127 expression were determined using flow cytometry.
Results:
CD4+CD45RO+, CD4+CD45RA+, CD4+ CD45RO+ CD127+, and CD4+CD45RA+CD127+T-cell counts in patients with good recovery were higher than in patients with poor recovery and those with general recovery patients (P <.05). Percentages of CD45RO+ were increased, and percentages of CD45RA+ and CD127 in T cells were decreased in patients with poor and general recovery (P <.05). CD127 values were positively correlated with CD4+T-cell counts and percentages of CD45RA+ subsets (P <.05).
Conclusion:
CD127 expression in T cells is decreased in patients with HIV-1 and is related to recovery of CD4+T-cell counts and to naïve subsets.

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
