CB-7 exhibits a weak TLR7 inhibiting effect in normal mice. The present invention provides a novel compound with a stronger TLR7 inhibiting effect than CB-7, a pharmaceutically acceptable salt of said compound, or a prodrug of said compound or salt. The present invention also provides a drug for the prevention or treatment of diseases associated with the activation of TLR7, said drug including the aforementioned TLR7 activation inhibitor.

The present invention provides broadly neutralizing antibodies against HIV, compositions comprising the same and methods of use thereof.

The present invention provides broadly neutralizing antibodies against HIV, compositions comprising the same and methods of use thereof.

Non-hormonal contraception compositions and methods for contraception are provided. One embodiment provides an antibody or an antigen binding fragment thereof that specifically binds to one or more sperm antigens and inhibits the ability of anti-body-bound sperm to fertilize an egg. Typically, the antibody is a monoclonal antibody, for example a human or humanized monoclonal antibody. In one embodiment, the antibody or antigen binding fragment thereof specifically binds to CD52g expressed on vertebrate, for example human, sperm cells and inhibits, blocks, or reduces the ability of the antibody-bound sperm to fertilize an egg. In one embodiment the antibody contains a membrane anchor. The membrane anchor can contain transmembrane domains, glycosylphosphatidylinositol anchors, or myristoylation motifs.

Human monoclonal antibodies directed against B7-H1 and uses of these antibodies in diagnostics and for the treatment of diseases associated with the activity and/or expression of B7-H1 are disclosed. Additionally, hybridomas or other cell lines expressing such antibodies are disclosed.

The invention relates to compositions including polynucleotides encoding polypeptides which have been chemically modified by replacing the uridines with 1-methyl-pseudouridine to improve one or more of the stability and/or clearance in tissues, receptor uptake and/or kinetics, cellular access by the compositions, engagement with translational machinery, mRNA half-life, translation efficiency, immune evasion, protein production capacity, secretion efficiency, accessibility to circulation, protein half-life and/or modulation of a cell's status, function, and/or activity.

A method of treating HIV comprising intramuscular administration once every 4 weeks or less frequently of a combination of cabotegravir or a pharmaceutically acceptable salt thereof and rilpivirine or a pharmaceutically acceptable salt thereof, including the option of discontinuing administration of a first oral anti-retroviral regimen and intramuscularly administering, once four weeks or less often said combination of cabotegravir and rilpivirine.

A method of treating HIV comprising intramuscular administration once every 4 weeks or less frequently of a combination of cabotegravir or a pharmaceutically acceptable salt thereof and rilpivirine or a pharmaceutically acceptable salt thereof, including the option of discontinuing administration of a first oral anti-retroviral regimen and intramuscularly administering, once four weeks or less often said combination of cabotegravir and rilpivirine.

The present invention provides a multi-drug-loading site and high drug-loading capacity ligand-drug conjugate. The ligand-drug conjugate has a structure of general formula (I). The ligand-drug conjugate has the characteristics of high loading capacity, high drug efficacy, low toxicity, and low risks. The ligand-drug conjugate can be used particularly to connect to a low toxicity chemical molecule, thereby extending a therapeutic window. Furthermore, the present invention provides an antibody-drug conjugate molecule. The antibody-drug conjugate molecule has the characteristics of multiple drug-loading ability and high drug-loading capacity, such that the antibody-drug conjugate can carry a large amount of a low toxicity chemical molecule and achieve a therapeutic effect without depending on antibody targeting or high toxicity chemicals.
