CHROMOPHORE-BASED MEDICAL SYSTEM FOR DETECTING GENETIC VARIATIONS IN ANALYTES
Medical systems for detecting a genetic variation in a polynucleotide analyte in a sample. A fluorophore is attached to a first primer, a quencher is attached to a second primer, and the first primer and the second primer are specific for the polynucleotide analyte. The primers are configured to amplify the polynucleotide analyte having the genetic variation and a corresponding polynucleotide analyte lacking the generic variation. There is a detectable difference between a change in signal generated by the fluorophore and quencher, and measured by a sensor of the medical system, when using the first and second primers to amplify the polynucleotide analyte with the genetic variation, and a change in signal generated by the fluorophore and quencher, and measured by the sensor of the medical system, when using the first and second primers to amplify the corresponding polynucleotide analyte lacking the genetic variation.
Primers, probes and methods for sensitive, specific detection and monitoring of HIV-1 and HCV
Primers and probes for detecting an RNA virus, including HIV, HIV-1 subtypes of the M and O groups, and HCV, in a sample. The primers and probes can be used for monitoring the efficacy of anti-retroviral treatment in a subject infected with HIV and/or HCV, and for detecting acute HIV-1 infection, and/or acute HCV infection, in a subject. Included are inner, middle and outer primers that can be used in PCR, including triple nested PCR in a single tube. The methods are highly sensitive and specific, allowing for detection of as few as 4 copies of virus in a sample.
Reagents and methods for analysis of HIV
The present invention is based in part on the present inventors' appreciation that certain sequences within an HIV genome are more likely to successfully detect HIV across a breadth of HIV variants. The ability to detect and/or quantify the presence and/or load of HIV in a subject is important to, among other things, the diagnosis and treatment of infected individuals. The present invention is based, in part, on the discovery of oligonucleotide reagents that detectably amplify sequences from a greater breadth of HIV samples than certain prior reagents and/or that generate amplicons from HIV genomes from which certain prior reagents would not have generated amplicons. Oligonucleotide reagents as described herein provide unexpected benefits in the detection and/or quantification of the presence and/or load of HIV in a subject, and thereby in the diagnosis and treatment of HIV.
METHODS OF IDENTIFYING HIV PATIENTS SENSITIVE TO THERAPY WITH GP120 V3 GLYCAN-DIRECTED ANTIBODIES
Provided are methods for identifying patient populations infected with HIV that can be targeted by antibodies that bind to HIV gp120 V3 glycan region.
Treatments to eliminate HIV reservoirs and reduce viral load
The present invention relates to a compound inducing activation of HLA-E-restricted CD8 T cells and/or NK cells in a human subject, and reducing HIV viral load, such as glatiramer acetate and glatiramer acetate related active substances and products, for use in the treatment of HIV infection. Macaques chronically infected by SIV have been treated with glatiramer acetate. One of the animals had already progressed to the stage of AIDS. We injected 18 mg of glatiramer acetate three times per week for only 2 weeks. Surprisingly, a strong impact on viral load was observed in response to the treatment. Viremia decreased by 1 log during glatiramer acetate treatment. Even more surprising was the fact that this decrease persisted after stopping the treatment reaching almost a 2 logs decrease in one animal. This is a major result as compared to cART as stopping cART leads to a rebound of the viral load within days. This decrease was correlated with activation of HLA-E restricted CD8 T cells, but not to other classical CD8+ T cells.
Compositions And Methods For Determining Resistance To Inhibitors Of Virus Entry Using Recombinant Virus Assays
The invention provides a method for determining whether a human immunodeficiency virus is resistant to a viral entry inhibitor. The methods are particularly useful for determining resistance to inhibitors that act by a non-competitive mechanism. In certain aspects, the methods comprise determining whether an HIV population is resistant to an HIV entry inhibitor, comprising determining a log-sigmoid inhibition curve comprising data points for entry of the HIV population in the presence of varying concentrations of the HIV entry inhibitor, wherein if the entry of the HIV population cannot be completely inhibited by the HIV entry inhibitor, the HIV population is resistant to the HIV entry inhibitor.
