In HIV/SIV-infected humans and rhesus macaques (RMs), a severe depletion of intestinal CD4(+) T-cells producing interleukin IL-17 and IL-22 associates with loss of mucosal integrity and chronic immune activation. However, little is known about the function of IL-17 and IL-22 producing cells during lentiviral infections. Here, we longitudinally determined the levels and functions of IL-17, IL-22...
BACKGROUND During acute HIV infection (AHI) HIV actively replicates but seroconversion has not yet occurred. Primary HIV infection (PHI) is characterized by a transient non-specific febrile illness, a massive inflammatory response and the progressive appearance of anti-HIV specific antibodies. In this study we have identified patterns of inflammatory biomarkers associated with the innate immuno...
Interleukin-15 (IL-15) Strongly Correlates with Increasing HIV-1 Viremia and Markers of Inflammation
OBJECTIVE IL-15 has been postulated to play an important role in HIV-1 infection, yet there are conflicting reports regarding its expression levels in these patients. We sought to measure the level of IL-15 in a large, well characterised cohort of HIV-1 infected patients and correlate this with well known markers of inflammation, including CRP, D-dimer, sCD163 and sCD14. DESIGN AND METHODS IL...
OBJECTIVE We investigated the relationship of the Herpesviridiae with inflammation and subclinical atherosclerosis in HIV-infected patients. METHODS Prospective study including virologically suppressed HIV-infected patients. IgG antibodies against herpesviruses, carotid intima-media thickness (cIMT), endothelial function through flow-mediated dilatation (FMD) of the brachial artery, and blood...
Even when antiretroviral therapy (ART) is started early after infection, HIV DNA might persist in the central nervous system (CNS), possibly contributing to inflammation, brain damage and neurocognitive impairment. Paired blood and cerebrospinal fluid (CSF) were collected from 16 HIV-infected individuals on suppressive ART: 9 participants started ART <4 months of the estimated date of infection...
BACKGROUND Successful highly active antiretroviral therapy (HAART) has changed the outcome of AIDS patients worldwide because the complete suppression of viremia improves health and prolongs life expectancy of HIV-1+ patients. However, little attention has been given to the immunological profile of patients under distinct HAART regimens. This work aimed to investigate the differences in the imm...
Cells of the myeloid lineage are significant targets for human immunodeficiency virus (HIV) in humans and simian immunodeficiency virus (SIV) in monkeys. Monocytes play critical roles in innate and adaptive immunity during inflammation. We hypothesize that specific subsets of monocytes expand with AIDS and drive central nervous system (CNS) disease. Additionally, there may be expansion of cells...
OBJECTIVE Rheumatoid arthritis (RA) accompanies infiltration and activation of monocytes in inflamed joints. We investigated dominant alterations of RA monocytes in bone marrow (BM), blood and inflamed joints. METHODS CD14+ cells from BM and peripheral blood (PB) of patients with RA and osteoarthritis (OA) were profiled with GeneChip microarrays. Detailed functional analysis was performed wit...
OBJECTIVES BIT225 (N-carbamimidoyl-5-(1-methyl-1H-pyrazol-4-yl)-2-naphthamide), a novel acyl-guanidine, is a novel antiviral drug that blocks Vpu ion channel activity and has anti-HIV-1 activity in vitro. The antiviral effect of BIT225 is most pronounced in cells of the myeloid lineage. With infected circulating monocytes and tissue-resident macrophages representing a key cellular reservoir of ...
OBJECTIVE Circulating oxidized low-density lipoprotein (oxLDL) levels are elevated in HIV-infected patients and have been associated with atherosclerosis. Statins have been shown to reduce plaque on coronary computed tomography angiography (cCTA) in HIV-infected individuals. Thus, we investigated the effect of statins on serum oxLDL levels and the relationship between changes in oxLDL and coron...
