Tuberculosis (TB) remains among the world's leading cause of mortality. For its control, studies of TB vaccines are needed. Since live-attenuated Mycobacterium bovis bacillus Calmette-Guérin (BCG) is the only TB vaccine currently in use, studies on the protective role of BCG are required. In this study, we analyzed host cells purified directly from whole blood of human immunodeficiency virus (HIV)-negative volunteers, comprising adult healthy donors (HD) and neonates (umbilical cord bloods, UCB), with the aim to directly compare in vitro immune responses with distinct BCG strains in human mononuclear cells...

BACKGROUND: Human immunodeficiency virus-infected individuals (HIVIIs) have a higher incidence of head and neck squamous cell carcinoma (HNSCC), and clinical and histopathological differences have been observed in their tumors in comparison with those of HNSCC patients without a human immunodeficiency virus (HIV) infection. The reasons for these differences are not clear, and molecular differences between HIV-related HNSCC and non-HIV-related HNSCC may exist. This study compared the mutational patterns of HIV-related HNSCC and non-HIV-related HNSCC...

REVIEW
Jaishree Naidoo, Nasreen Mahomed, Halvani Moodley
The epidemiology of tuberculosis is adversely impacted by the human immunodeficiency virus (HIV) coinfection. HIV-infected patients are more prone to opportunistic infections, most commonly tuberculosis, and the risk of death in coinfected patients is higher than in those without HIV. Due to the impaired cellular immunity and reduced immunological response in HIV-infected patients, the classic imaging features of tuberculosis usually seen in patients without HIV may present differently. The aim of this review article is to highlight the imaging features that may assist in the diagnosis of tuberculosis in patients with HIV coinfection...

People living with the human immunodeficiency virus (HIV) should receive pneumococcal vaccinations as part of their routine health maintenance. Our goal was to create a "virtual clinic" to help increase rates of pneumococcal vaccination among people living with HIV without adding substantially to the workload of primary providers. We used administrative data from our Veterans Affairs (VA) medical center to identify a cohort of veterans living with HIV who were not current with either the 13-valent pneumococcal conjugate vaccine (PCV13), the 23-valent pneumococcal polysaccharide vaccine (PPSV23) or both...

The clinical use of endothelial colony forming cells (ECFC) is hampered by their restricted engraftment. We aimed to assess engraftment, vasculogenic and pro-angiogenic activities of ECFC in immunocompetent (C57BL/6: WT) or immunodeficient (rag1 (-/-) C57BL/6: Rag1) mice. In addition, the impact of host immune system was investigated where ECFC were co-implanted with mesenchymal stem/stromal cells (MSC) from adult bone marrow (AdBM-MSC), fetal bone marrow (fBM-MSC), fetal placental (fPL-MSC), or maternal placental (MPL-MSC)...

The present study examined the expression and biological functions of bromodomain-containing protein 4 (BRD4) in skin squamous cell carcinoma (SCC) cells. Our results show that BRD4 mRNA and protein expression was upregulated in human skin SCC cells, as compared to its level in the normal skin keratinocytes and fibroblasts. Treatment with BRD4 inhibitors, JQ1 and CPI203, resulted in proliferation inhibition, apoptosis and cell cycle arrest in both established (A431 cell line) and primary skin SCC cells. Furthermore, BRD4 knockdown (by targeted shRNAs) or knockout (by CRISPR/Cas9) largely inhibited A431 cell proliferation...

Background Chronic granulomatous disease (CGD) is a hereditary immunodeficiency caused by mutations in genes encoding nicotinamide adenine dinucleotide phosphate oxidase enzyme complex, which lead to the inability to kill intracellular pathogens. Patients with CGD are susceptible to recurrent bacterial and fungal infections in their early lives. Although the recent survival rate has been significantly improved, early diagnosis is critical to prevent multiple organ impairment. In 1950s, CGD was first described as a disease with recurrent infections and visceral infiltration of granulomas and pigmented histiocytes...

In colorectal cancer (CRC), RHAMM is an independent adverse prognostic factor. The aim of the study was therefore to investigate on the role of RHAMM as a potential direct driver of cell proliferation and migration in CRC cell lines and to identify pathways dependent on RHAMM in human CRC. Proliferation, cell cycle alterations and invasive capacity were tested in two RHAMM- and control- knockdown CRC cell lines by flow cytometry and in vitro assays. Tumorigenicity and metastasis formation was assessed in immunodeficient mice...

This study comparatively investigated the transcriptional, physiological, and phenotypic differences of the immune disorder between severe combined immunodeficient (SCID) mouse and pig models. We discovered that the recombination activating gene-2 (Rag-2) SCID mice, but not RAG-2 SCID pigs, showed intense, infrequent, and mild cluster of CD3(+)-, CD4(+)-, and CD8(+) signals respectively, suggesting that distinct species-specific effects exist. Furthermore, the expression of six relevant genes (NFATC1, CD79B, CD2, BLNK, FOXO1, and CD40) was more downregulated than that in the Rag-2 SCID mice, which provides a partial rationale for the death of T/B cells in the lymphoid organs of RAG-2 SCID pigs but not in Rag-2 SCID mice...

Human immunodeficiency virus type 1 (HIV-1) envelope gp120 is partly an intrinsically disordered (unstructured/disordered) protein as it contains regions that do not fold into well-defined protein structures. These disordered regions play important roles in HIV's life cycle, particularly, V3 loop-dependent cell entry, which determines how the virus uses two coreceptors on immune cells, the chemokine receptors CCR5 (R5), CXCR4 (X4) or both (R5X4 virus). Most infecting HIV-1 variants utilise CCR5, while a switch to CXCR4-use occurs in the majority of infections...

Diagnoses of human immunodeficiency virus (HIV) infection among women declined 17% during 2011-2015, and a total of 7,498 women received a diagnosis of HIV infection in 2015 (1). Although black or African American (black) women accounted for only 12% of the U.S. female population, 60% of women with newly diagnosed HIV infection were black (1,2). By the end of 2014, an estimated 255,900 women were living with HIV infection (3), including approximately 12% who did not know they were infected; in addition, approximately 45% of women who had received a diagnosis had not achieved viral suppression (3)...

Background: Tuberculosis (TB) remains a leading cause of death in children globally. It is recognized that human immunodeficiency virus (HIV) infection increases the risk of developing TB, but our understanding of the impact of HIV on risk of mortality for children treated for TB is limited. We aimed to identify predictors of mortality in children treated for drug-susceptible TB. Methods: A retrospective analysis of all children (<15 years of age) routinely treated between 2005 and 2012 for drug-susceptible TB in Cape Town was conducted using the programmatic electronic TB treatment database...

Background: Patients with human immunodeficiency virus/AIDS-associated cryptococcal meningitis (CM) frequently experience clinical deterioration, known as cryptococcosis-associated immune reconstitution inflammatory syndrome (C-IRIS), upon initiation of antiretroviral therapy (ART). The immunological mechanisms underlying C-IRIS are incompletely defined and no reliable predictive biomarkers exist. We investigated whether plasma or cerebrospinal fluid (CSF) levels of cytokines and chemokines predicted C-IRIS and are potential predictive biomarkers...

Part of the susceptibility to tuberculosis has a genetic basis, which is clear in primary immunodeficiencies, but is less evident in apparently immunocompetent subjects. Immune responses were analysed in blood samples from tuberculosis patients and their healthy first-degree relatives who were infected in vitro with mycobacteria (either Mycobacterium tuberculosis or M. bovis BCG). The antimicrobial activity against M. tuberculosis in blood from relatives was significantly lower than that observed in healthy controls...
