Article Abstract
Background: HIV DNA mirrors the number of infected cells and the size of the HIV viral reservoir. The aim of this study was to evaluate the effect of pre-cART HIV DNA levels as a predictive marker of immune reconstitution and on the post-cART CD4 counts trends.
Methods: HIV DNA was isolated from PBMCs and quantified by real-time PCR. Immune reconstitution was assessed up to four years. Piecewise-linear mixed models were used to describe CD4 count changes.
Results: 148 people living with HIV (PLWH) were included. The highest rate of immune reconstitution was observed during the first trimester. There was a trend showing that high HIV RNA level resulted in greater increase in CD4 count, especially during the first trimester of cART (difference above vs. below median 15.1 cells/μL/month; 95% CI -1.4-31.5; = 0.073). Likewise, higher HIV DNA level would predict greater CD4 increases, especially after the first trimester (difference above vs. below median 1.2 cells/μL/month; 95% CI -0.1-2.6; = 0.071). Higher DNA and RNA levels combined were significantly associated with greater CD4 increase past the first trimester (difference high/high vs. low/low 2.1 cells/μL/month; 95% CI 0.3-4.0; = 0.024). In multivariable analysis, lower baseline CD4 counts predicted a greater CD4 rise.
Conclusions: In successfully treated PLWH, pre-cART HIV DNA and HIV RNA levels are predictors of immune reconstitution.

The tumor microenvironment (TME) plays a pivotal role in cancer progression, though the molecular regulators governing its immunosuppressive properties remain incompletely characterized. In this study, we identify Makorin-2 (MKRN2) as a novel modulator of TME remodeling through integrated analyses of genetically engineered mouse models and human clinical data. Utilizing MKRN2 knockout mice, we observed significantly accelerated tumor growth compared to wild-type control, which was associated with profound alterations in immune cell composition, especially M2 macrophages.

Hematopoietic stem cells (HSCs) responsible for blood cell production and their bone marrow regulatory niches undergo age-related changes, impacting immune responses and predisposing individuals to hematologic malignancies. Here, we show that the age-related alterations of the megakaryocytic niche and associated downregulation of Platelet Factor 4 (PF4) are pivotal mechanisms driving HSC aging. PF4-deficient mice display several phenotypes reminiscent of accelerated HSC aging, including lymphopenia, increased myeloid output, and DNA damage, mimicking physiologically aged HSCs.

Immune reconstitution inflammatory syndrome (IRIS) is commonly described in individuals recovering from immunosuppression, particularly in HIV-positive patients initiating antiretroviral therapy. However, a similar rebound phenomenon can occur postpartum, a period marked by a shift from an immunotolerant to a pro-inflammatory state. IRIS in this context is underrecognized and may present atypically, complicating timely diagnosis.

Extrapulmonary tuberculosis (TB), particularly when it involves the central nervous system (CNS), remains a significant clinical challenge. Cerebral tuberculoma, though rare, can present with complex symptoms that overlap with other neurological conditions, making timely diagnosis difficult. The condition demands a multidisciplinary approach for accurate diagnosis and effective management, especially in patients with multiple comorbidities.

The aim of this study was to establish a humanized immune system model in severe combined immunodeficient (SCID) mice, assess dendritic cell (DC) phenotype, and evaluate the therapeutic efficacy of a DC-based vaccine in a bladder cancer model. Bladder cancer was induced in SCID mice by injection of T24 cells, followed by human peripheral blood leukocyte (hu-PBL) inoculation to reconstitute the human immune system. DCs were generated in vitro by culturing hu-PBL for 5 days and matured on the eighth day.
