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 (CD4T < 350/μ;L, patients with general recovery (CD4T = 350 - ∼600/μL) and patients with good recovery (CD4T > 600/μL). Counts and percentages of naïve (CD45RA) and memory (CD45RO) T cells and CD127 expression were determined using flow cytometry.
Results: CD4CD45RO, CD4CD45RA, CD4 CD45RO CD127, and CD4CD45RACD127T-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 CD4T-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 CD4T-cell counts and to naïve subsets.

Background: Regulatory T cells (Tregs) are found to be critical for maintaining immune tolerance to self-antigens; however, their status in primary Sjögren's syndrome (pSS) remains unclear. We investigated alterations in the abundance of peripheral Tregs in a large pSS cohort and their implications for patients.
Methods: Levels of CD4+CD25+FOXP3+Treg cells in the peripheral blood of 624 patients with pSS, and 93 healthy controls (HCs) were detected using modified flow cytometry (FCM).

Background: Dysregulation of immune responses may influence the progression of metabolic dysfunction-associated steatotic liver disease (MASLD) to metabolic dysfunction-associated steatohepatitis (MASH). Our recent data suggest the role of Th17-related cytokines in fibrosis advancement in MASLD. Herein, we aimed to analyze T-regulatory and Th17-producing T-lymphocytes by flow cytometry with respect to MASLD progression.

As a result of the growing use of nuclear energy and radiation in medical interventions within the last decade, the potential for radiation exposure among the general public has increased. Exposure to high doses of radiation severely impairs the immune system, including CD8 T cells. While the effects on the naïve and primary memory (1M) CD8 T cell pools have been partially characterized, the effect of radiation exposure on CD8 T cell memory generated after repeated antigen (Ag) exposures has not.

Itch is the dominant symptom in atopic dermatitis (AD). Cutaneous neuronal alterations underlying this symptom are still poorly understood. Therefore, we aimed at deciphering cutaneous neuronal alterations during AD treatment with dupilumab.

Introduction: Clinical studies of T cells engineered with chimeric antigen receptor (CAR) targeting CD19 in B-cell malignancies have demonstrated that relapse due to target antigen (CD19) loss or limited CAR T cell persistence is a common occurrence. The possibility of such events is greater in solid tumors, which typically display more heterogeneous antigen expression patterns and are known to directly suppress effector cell proliferation and persistence. T cell engineering strategies to overcome these barriers are being explored.
