Abstract: Described herein, in one aspect, are antigen presenting cells (APCs) comprising an exogenous nucleic acid encoding one or more candidate antigens, wherein the one or more candidate antigens are expressed and presented with MHC class I or MC class II molecules; a molecular reporter of Granzyme B (GzB) activity; and c) an exogenous inhibitor of caspase-activated deoxyribonuclease (CAD)-mediated DNA degradation, a CAD knockout, or a caspase knockout (e.g., caspase 3 knockout). Described herein, in another aspect, is a system for detection of recognized antigen presentation by an antigen presenting cell to a cytotoxic lymphocyte or NK cell.

Abstract: The present invention provides compositions, including vectors, and methods for the rapid subcloning of nucleic acid sequences in vivo and in vitro. In particular, the invention provides vectors used to contain a gene of interest that comprise a sequence-specific recombinase target site. These vectors are used to rapidly transfer the gene or genes of interest into any vector that contains a sequence-specific recombinase target site located downstream of a regulatory element so that the gene of interest may be regulated.

Abstract: Disclosed herein are methods for treating and/or preventing HIV infection in a cell. The methods involve downmodulating one or more of the HIV-dependency factors (HDFs) disclosed herein to thereby treat and/or prevent HIV infection in the cell. Downmodulating the HDFs can be by contacting the cell with an agent that downmodulates the HDF. Also disclosed herein are methods for treating and/or preventing HIV infection in a subject comprising downmodulating one or more of the HIV-dependency factors (HDFs), disclosed herein, to thereby treat and/or prevent HIV infection in the subject. The method may further comprise selecting a subject diagnosed with or at risk for HIV infection, prior to downmodulating. Downmodulating the HDFs may comprise administering an agent that downmodulates the HDF to the subject such that the agent contacts HIV host cells of the subject. The agent may inhibit HDF gene expression, protein synthesis, HDF function or HDF activity, or combinations thereof.

Abstract: The present invention is directed to retroviral vectors, and libraries generated from the vectors that can be used in assessing the stability of proteins and in correlating degradation with a specific E3 ubiquitin ligase. The libraries can also be used to identify factors that alter the degradation of proteins of therapeutic value and which have potential use clinically.

Abstract: This invention provides barcoded shRNA libraries and methods of using same.

Abstract: The present invention is directed methods for cloning DNA by homologous recombination. The methods can be used without a need for ligases or restriction enzymes and allow for the rapid alignment of multiple DNA fragments.
