This disclosure relates to binding agents with specificity for programmed cell death 1 (PD-1) and to methods for using the same to treat, prevent and / or ameliorate an infectious disease (e.g., human immunodeficiency virus (HIV)), cancer and / or autoimmunity.

Peptides exhibiting anti-viral and anti-fusogenic activity are modified to provide greater stability and improved half-life in vivo. The selected peptides include fusion inhibitors DP178 and DP107 and related peptides and analogs thereof. The modified peptides are capable of forming covalent bonds with one or more blood components, preferably a mobile blood component.

Compounds, methods and compositions for treating a host infected with human immunodeficiency virus and hepatitis B virus comprising administering an effective amount of a described 4′-C-substituted β-D- and β-L-nucleoside or a pharmaceutically acceptable salt or prodrug thereof, are provided.

Methods are provided for screening natural and synthetic anti-HIV agents using recombinant cells that are rendered susceptible to productive infection of various strains, subtypes or clades of HIV from both laboratory and clinical isolates. The method comprises: taking a culture of recombinant cells in which at least one of the recombinant cells comprises a reporter sequence comprising a reporter gene whose expression is regulated by a protein specific to HIV, and a heterologous sequence which encodes CD4 and one or more additional cell surface receptors, wherein the heterologous sequence expresses CD4 and the one or more additional cell surface receptors at elevated levels as compared to the cell in the absence of expression by the heterologous sequence such that productive infection of the recombinant cell by HIV is achieved, which is defined by HIV viral replication and the infection of non-infected cells in the culture of the recombinant cells; contacting the cell culture with a sample containing HIV; adding a tester agent to the cell culture; and detecting a change in a level of expression of the reporter gene in the cells in the culture.

Immunological reagents obtained from multimeric forms of the HIV-2 and SIV envelope glycoproteins and their use in the detection of HIV-2, particularly, the HIV-2 proteins gp300, p200, p90, and p80, and gp300 of SIV.
