In this report, we describe an investigation of the effects of Lutzomyia longipalpis sand fly salivary gland homogenates (SGH) on cytokine production and expression of costimulatory molecules on human monocytes, macrophages (Mphis), and dendritic cells (DCs). SGH of L. longipalpis induced an increase in interleukin-6 (IL-6), IL-8 and IL-12p40 production but(More)
Even though the treatment of human immunodeficiency virus (HIV)-infected individuals with highly active antiretroviral therapy (HAART) provides a complete control of plasma viremia to below detectable levels (<40 copies/mL plasma), there is an unequal distribution of all antiretroviral drugs across diverse cellular and anatomic compartments in vivo. The(More)
We demonstrate for the first time that the genome-wide profiling of HIV-infected peripheral blood mononuclear cells (PBMCs) from HIV-patients free of neurologic disease show overrepresentation of neurodegenerative pathways (Alzheimer’s, Parkinson’s, ALS, Huntington’s and Prion Disease, etc.) in genome-wide microarray analysis, which suggests that this(More)
T cell-mediated immunity is critical in resistance against Leishmania parasites, and T cell activation requires signals provided by costimulatory molecules. Herein we evaluated the role of costimulatory molecules on cytokine production and T cell surface molecule expression by peripheral blood mononuclear cells (PBMC) from cutaneous leishmaniasis (CL)(More)
Despite significant contributions of monocytes to HIV persistence, the genomic basis of HIV-infection of monocytes and its association with plasma viremia remain elusive. To understand HIV interactions with monocytes during disease progression, monocytic transcriptomes from long-term non-progressors (LTNP), HIV+ patients with viral load <1000, with viral(More)
PURPOSE OF REVIEW Immunomonitoring technologies are not only fast changing, but also have already revolutionized the way we look at treatments, diagnosis, and prognosis of a given disease. The purpose of the review is to provide a recent update on the use or possible use of array-based data in immunomonitoring of HIV patients. RECENT FINDINGS Since the(More)
The potential involvement of host microRNAs (miRNAs) in HIV infection is well documented, and evidence suggests that HIV modulates and also dysregulates host miRNAs involved in maintaining the host innate immune system. Moreover, the dysregulation of host miRNAs by HIV also effectively interferes directly with the host gene expression. In this study, we(More)
BACKGROUND HIV p24 is an extracellular HIV antigen involved in viral replication. Falling p24 antibody responses are associated with clinical disease progression and their preservation with non-progressive disease. Stimulation of p24 antibody production by immunization to delay progression was the basis of discontinued p24 vaccine. We studied a(More)
