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

Provided are a bispecific antibody and use thereof. The bispecific antibody comprises a B7-H4-targeting antigen-binding domain and a 4-1BB-targeting antigen-binding domain. The bispecific antibody has one or two or three sites for binding to 4-1BB, along with a novel fully human B7-H4 antibody. The bispecific antibody specifically binds to tumor cells by targeting B7-H4, reducing toxicity induced by 4-1BB activation. In addition, the bispecific antibody of the present invention comprises a human Fc fragment, and thus retains the binding of Fc to FcRn and has a longer half-life.

Provided herein are antibodies binding to LILRB1 and the uses of the antibodies in detecting and treating cancer and autoimmune diseases.

Provided herein are methods for the treatment of cancers with antibody drug conjugates (ADC) that bind to 191P4D12 proteins.

Disclosed herein are compositions and methods for the treatment of one or more progressive lung diseases, which may include, but are not limited to, chronic obstructive pulmonary disease (COPD), emphysema, and AAT deficient lung disease. The compositions useful for the disclosed methods may include an an antigen binding protein such as an anti-CELA1 antibody, an anti-CELA1 scFv, or an anti-CELA1 antisense nucleotide (ASO), which may be administered in an amount sufficient to treat one or more of the aforementioned disease states.

The present disclosure relates to methods of treating or preventing hereditary angioedema (HAE) in a subject in need thereof by subcutaneously administering to the subject an effective amount an anti-FXII antibody comprising (i) a V.sub.H comprising a CDRH1 comprising a sequence set forth in SEQ ID NO:1; a CDRH2 comprising a sequence set forth in SEQ ID NO:2; and a CDRH3 comprising a sequence set forth in SEQ ID NO:3; and (ii) a V.sub.L comprising a CDRL1 comprising a sequence set forth in SEQ ID NO:4; a CDRL2 comprising a sequence set forth in SEQ ID NO:5; and a CDRL3 comprising a sequence set forth in SEQ ID NO:6.

The present invention relates to novel antibodies or antigen-binding fragments thereof that specifically bind to TransMembrane 4 Superfamily Member 4 (TM4SF4). These antibodies or antigen-binding fragments thereof exhibit proliferation inhibitory activity of cancer cells so as to effectively prevent or treat cancer, and reduce the self-renewal ability of cancer stem cells to be usefully used even in the treatments of cancer with a poor prognosis in conventional anticancer treatments.

Disclosed herein are anti-mesothelin antibodies and antigen-binding fragments, chimeric antigen receptors (“CARs”) having these anti-mesothelin antibodies and antigen-binding fragments (“mesothelin CARs”) and genetically modified immune effector cells having such mesothelin CARs. Polynucleotides encoding the anti-mesothelin antibodies and antigen-binding fragments and mesothelin CARs are also provided herein. Compositions comprising anti-mesothelin antibodies and antigen-binding fragments and mesothelin CARs are also provided herein. The present disclosure also relates to uses of the anti-mesothelin antibodies and antigen-binding fragments and genetically modified immune effector cells having such mesothelin CARs in cancer treatment.

Disclosed are antigen binding polypeptides and antigen binding polypeptide complexes (e.g., antibodies and antigen binding fragments thereof) having certain structural features. Also disclosed are polynucleotides and vectors encoding such polypeptides and polypeptide complexes; chimeric antigen receptors (CARs), cells, pharmaceutical compositions and kits containing such polypeptides and polypeptide complexes; and methods of using such polypeptides and polypeptide complexes.

Antibodies and compositions against IGF-1R and uses thereof are provided herein.
