The present invention relates to the use of a nucleic acid molecule encoding a first reporter gene, bordered by at least one first pair and one second pair of sequences targeting a site-specific recombinase in order to detect cells of a mammal infected with a virus responsible for an immunodeficiency.

The present invention relates to antibody derivatives against HIV based on a mutated CD4-IgG scaffold with enhanced antiviral and immunomodulatory activities. These antibody derivatives are characterized for having an increased ability to (i) block the entry of human immunodeficiency virus (HIV) into host cells and (ii) elicit effector functions through the activation of natural killer (NK) cells. The present invention further relates to nucleic acids, vectors and host cells expressing said antibody derivatives, as well their therapeutic and diagnostic applications in human health.

Multiplexed test measurements are conducted using an assay module having a plurality of assay domains. In preferred embodiments, these measurements are conducted in assay modules having integrated electrodes with a reader apparatus adapted to receive assay modules, induce luminescence, preferably electrode induced luminescence, in the wells or assay regions of the assay modules and measure the induced luminescence.

The present disclosure relates to the field of medical diagnosis, and specifically, relates to a synthetic peptide for detecting HIV-1. The synthetic peptide is obtained by mutating the amino acid sequence set forth as SEQ ID NO: 1. The synthetic peptide can better detect anti-HIV-1 antibodies, and can better avoid potential “false negative” and “false positive” results.

Disclosed are compositions comprising an interferon-alpha binding protein and combined anti-retroviral therapy (cART). In some aspects, the interferon-alpha binding protein is B18R. In some aspects, the compositions further comprise a pharmaceutically acceptable carrier. Disclosed are methods of treating a subject with HIV associated neurogenerative disorder (HAND) comprising administering a therapeutically effective amount of B18R and cART. Disclosed are methods of reversing behavioral abnormalities in subjects having HAND comprising administering a therapeutically effective amount of B18R.

The present invention provides compositions and methods that can be used to determine a peptide signature for an antibody repertoire in a sample comprising multiple antibodies. The method can be used to characterize a phenotype in a sample, such as providing a diagnosis, prognosis or theranosis of a medical condition.

Disclosed are methods to measure the extent of viral infection and methods to measure latent viral reservoir in cells harboring or suspected of harboring such a reservoir.

Broadly neutralizing antibodies against HIV-1 which specifically bind to gp120 of HIV-1, a method of preparing such antibodies and the use thereof are provided.

A major immune dysfunction persisting in chronic diseases such as HIV infection and cancer is the impairment of T cell motility and migration to tissues. Therapeutics such as antiretroviral therapy or cancer therapy frequently do not fully restore T cell motility for tissue migration and infiltration. Cofilin is an actin-depolymerizing factor that regulates actin dynamics for T cell migration. Here we demonstrate that the levels of cofilin phosphorylation in blood T cells (CD4 or CD8), macrophages, B cells, natural killer (NK) cells, and/or cancer cells can be used to quantify the immune damages caused by chronic viral infection and cancer, and to predict the recovery of T cells following treatment.

The presently-disclosed subject matter relates to crosslinkers, compositions, and methods for trapping a target of interest on a substrate of interest. The methods may be used to inhibit and treat pathogen infection and provide contraception. The methods may be used to trap or separate particles and other substances. The subject matter further relates to methods of identifying and preparing optimal crosslinkers and methods for manipulating targets of interest.
