Disclosed herein is a personalized tumor vaccine comprising attenuated cancer cells and a method of using said personalized tumor vaccine to treat cancer.

The present invention is based, in part, on the discovery of anti-LRRC25 compositions (e.g., monoclonal antibodies and antigen-binding fragments thereof), that regulate inflammatory phenotypes of myeloid cells, such as suppressive myeloid cells, monocytes, macrophages, neutrophils, and/or dendritic cells, including polarization, activation, and/or function, and methods of using such anti-LRRC25 compositions for therapeutic, diagnostic, prognostic, and screening purposes.

Methods for producing mono-specific immunoglobin Y (IgY) antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are disclosed. IgY antibodies are found in birds and can be isolated from egg yolk of chicken eggs. Hens are immunized with a SARS-CoV-2 spike protein comprising an ACE2 receptor binding domain (RBD). IgY antibodies against the RBD are isolated from eggs laid by the hens. The isolated RBD-IgY antibodies were tested in vitro in mammalian cells, wherein the RBD-IgY blocked SARS-CoV-2 infection of the cells. A pharmaceutical composition comprising the mono-specific IgY antibodies can be used to inhibit or treat COOVID-19, the SARS-CoV-2 infection. IgY antibodies are generally regarded as safe and offer various production and treatment advantages when compared to mammalian antibodies.

Herein is reported an anti-transferrin receptor antibody that specifically binds to human transferrin receptor and cynomolgus transferrin receptor, which comprises i) a humanized heavy chain variable domain derived from the heavy chain variable domain of SEQ ID NO: 01, and ii) a humanized light chain variable domain derived from the light chain variable domain of SEQ ID NO: 26, wherein the antibody has an off-rate for the human transferrin receptor that is equal to or less than (i.e. at most) the off-rate of the anti-transferrin receptor antibody 128.1 for the cynomolgus transferrin receptor, whereby the off-rates are determined by surface plasmon resonance, and whereby the anti-transferrin receptor antibody 128.1 has a heavy chain variable domain of SEQ ID NO: 64 and a light chain variable domain of SEQ ID NO: 65.

The present invention relates to an antibody and antibody fragment that specifically binds to OX40 and to a composition comprising said antibody or antibody fragment thereof. In addition, the present invention relates to a nucleic acid encoding the antibody or antibody fragment thereof and a host cell comprising the same, and to a related use thereof. In addition, the present invention relates to the use of the antibody and antibody fragment for treatment and diagnosis.

Provided herein are antibodies, or antigen binding portions thereof, that bind to glucocorticoid-inducible TNF receptor (GITR). Also provided are uses of these proteins in therapeutic applications, such as in the treatment of cancer. Further provided are cells that produce the antibodies, polynucleotides encoding the heavy and/or light chain variable region of the antibodies, and vectors comprising the polynucleotides encoding the heavy and/or light chain variable region of the antibodies.

The present invention relates to mouse antibodies that bind to angiopoietin-2 (Ang2), humanized anti-Ang2 antibodies derived therefrom, and the use thereof. The anti-Ang2 antibodies have a dual function of activating the Tie2 receptor together with neutralizing Ang2. The anti-Ang2 antibodies show the property of normalizing abnormal and pathological blood vessels, and thus exhibits therapeutic efficacy against various diseases and disorders associated with abnormal blood vessels. The present invention further provides an angiogenesis inhibitor and a composition for treatment of diseases associated with abnormal Ang2 expression and Tie2 dysregulation, which comprise the antibody as an active ingredient, and a composition for diagnosing diseases associated with Ang2 inhibition and Tie2 activation, which comprises the antibody.

This invention relates to a method for treating cancer by administering a CDK4/6 inhibitor or CDK2/4/6 inhibitor in combination with a 4-1BB agonist and/or an OX40 agonist to a subject in need thereof.

This disclosure relates to anti-Natriuretic Peptide Receptor 1 (NPR1) antibodies including agonist antibodies which are able to activate the NPR1 receptor, pharmaceutical compositions comprising the same, and methods of treatment comprising the same.

An isolated antigen-binding protein, having one or more of the following properties: 1) capable of binding to human and monkey-derived GITR proteins at a K.sub.D value of 7×10.sup.−12 or below, wherein the K.sub.D value is measured by BLI method; 2) capable of stimulating immune cell proliferation; 3) capable of stimulating immune cells to secrete IFN-γ, wherein the secretion is measured in T cell viability assay; 4) capable of inhibiting tumor growth and/or tumor cell proliferation; 5) capable of activating GITR signaling pathway; 6) capable of inhibiting the binding of GITR to GITRL.
