Natural killer (NK) cells specialize in killing virally infected- or tumor cells and are part of the innate immune system. The activational state of NK cells is determined by the balance of incoming activating and inhibitory signals mediated by receptor-ligand binding with the target cell. These receptor-ligand bonds mainly consist of the killer immunoglobulin-like receptors (KIR), which are expressed at the cell surface of NK cells, and their ligands: the highly variable human leukocyte antigen -class I molecules (HLA)...

BACKGROUND: Previous studies with BIT225 (N-carbamimidoyl-5-(1-methyl-1H-pyrazol-4-yl)-2-naphthamide) have demonstrated a unique antiviral activity that blocks the release of HIV-1 from monocyte-derived macrophages (MDM). Antagonising the ion channel formed by HIV-1 Vpu, BIT225 preferentially targets de novo intracellular virus produced in 'virus-containing compartments' of MDM. In primary infections, dendritic cells (DC) are one of the first cells infected by HIV-1 and can transfer virus to more permissive CD4(+) T cells, making these cells an important target for novel antiviral therapies...

Many neurodegenerative diseases are accompanied by metabolic disorders. CCL5/RANTES, and its receptor CCR5 are known to contribute to neuronal function as well as to metabolic disorders such as type 2 diabetes mellitus, obesity, atherosclerosis and metabolic changes after HIV infection. Herein, we found that the lack of CCR5 or CCL5 in mice impaired regulation of energy metabolism in hypothalamus. Immunostaining and co-immunoprecipitation revealed the specific expression of CCR5, associated with insulin receptors, in the hypothalamic arcuate nucleus (ARC)...

BACKGROUND: The preferred regimen for HIV post-exposure prophylaxis (PEP) is based mainly on safety and tolerability because it is given to immunocompetent people without HIV infection for a limited time (28 days). The frequency of adverse events (AEs) may be > 60%. Although AEs are generally not severe, they can lead to lack of adherence and failure to complete the regimen. We evaluated the co-formulation elvitegravir, cobicistat, emtricitabine, and tenofovir disoproxil fumarate (Stribild(®)) prescribed as one pill taken once daily for HIV PEP in terms of tolerability and adherence...

SETTING: Although there is ample evidence that smoking increases the risk of tuberculosis (TB), the magnitude of impact on TB risk among HIV-infected persons is poorly described. Given that a high proportion of patients with TB are co-infected with HIV in South Africa, the risks arising from the intersection of smoking, TB, and HIV/AIDS have key relevance for tobacco control policies. OBJECTIVE: To evaluate the association of pulmonary tuberculosis (PTB) with current tobacco smoking among men with HIV in South Africa...

Bowen's disease (BD) is a form of squamous cell carcinoma in situ often associated with human papillomavirus. Co-infection with human immunodeficiency virus (HIV) is associated with a greater risk of malignancy. We describe a case of BD in a 52-year-old unmarried HIV-positive male who presented with extensive skin lesions of 1-year duration. Histopathology was suggestive of BD. He had been tried with topical imiquimod cream and cryo-therapy for 6 months. We observed no response for these above therapies. He was started on with anti-retroviral therapy (ART) as his CD4 count was 253 cells/mm(3)...

Leishmaniasis is caused by protozoan parasite of genus leishmania. Visceral leishmaniasis, diffuse cutaneous leishmaniasis, and atypical forms of cutaneous leishmaniasis are common in HIV-infected patients. Our patient presented with an obstructive mass in nasal cavity and was diagnosed as a case of mucocutaneous leishmaniasis. Spontaneous healing of lesions in HIV-infected patients is rare rather they are unresponsive to treatment and have frequent relapses, especially in patients with low CD4 count. However, in our patient, the lesion improved significantly after 2 months of highly active antiretroviral therapy and co-trimoxazole prophylaxis...

Acquired immuno deficiency syndrome (AIDS) associated Kaposi's sarcoma (KS) is one of the clinical forms of KS. KS is caused by human herpes viruses 8 or KS associated herpes virus (KSHV). In India, till now, only 16 cases of AIDS associated KS was reported. Of all the clinical forms of KS, AIDS associated KS is distinct in many ways viz.; cutaneous manifestations commonly affects face and trunk rather than lower limbs, more mucosal lesions, rapidly progressive, and early systemic involvement. When human immunodeficiency virus (HIV) is co-infected with KSHV, in addition to the other pathogenic factors for the development of KS, HIV Tat protein promotes the proliferation of cytokine-activated endothelial cells and stimulates KS...

INTRODUCTION: Cigarette smoking is one of the major risk factors for non-AIDS related morbidities and is highly prevalent among HIV infected people. However, no reports exist from Tanzania, one of the countries highly affected by the HIV pandemic and one of Africa's biggest tobacco producer. METHODS: We examined the patterns and prevalence of cigarette smoking among HIV and TB co-infected adult patients in Dar es Salaam using a cross sectional study design. Proportions were used to describe the pattern of cigarette smoking...

Combining phylogenetic and network methodologies has the potential to better inform targeted interventions to prevent and treat infectious diseases. This study reconstructed a molecular transmission network for people with recent hepatitis C virus (HCV) infection and modelled the impact of targeting directly acting antiviral (DAA) treatment for HCV in the network. Participants were selected from three Australian studies of recent HCV from 2004 to 2014. HCV sequence data (Core-E2) from participants at the time of recent HCV detection were analysed to infer a network by connecting pairs of sequences whose divergence was ≤...

: Despite the success in viral inhibition and CD4 T cell recovery by highly active antiretroviral treatment (HAART), HIV-1 is still not curable due to the persistence of HIV-1 reservoir during treatment. One patient with acute myeloid leukemia who received allogeneic hematopoietic stem cell transplantation from homozygous CCR5 Δ32 donor has had no detectable viremia for 9 years after HAART cessation. This case has inspired a field of HIV-1 cure research focusing on engineering HIV-1 resistance of permissive cells...

BACKGROUND: Infection with human immunodeficiency virus (HIV) influences the outcome and natural disease progression of hepatitis C virus (HCV) infection. While the majority of HCV mono-infected and HCV/HIV co-infected subjects develop chronic HCV infection, 20-46% of mono- and co-infected subjects spontaneously clear HCV infection. The mechanism underlying viral clearance is not clearly understood. Analysis of differential cellular gene expression (mRNA) between HIV-infected patients with persistent HCV infection or spontaneous clearance could provide a unique opportunity to decipher the mechanism of HCV clearance...
