Described herein are monoclonal antibodies that bind to VSIG-4 including antibodies that block the binding of VSIG-4 to SIGLEC-7, compositions including the monoclonal antibodies, and methods of making and using those antibodies and compositions.

Herein is reported that for transient transfections the use of the human elongation factor 1 alpha promoter (with Intron A) provides for an enhanced productivity (in LC-HC-SM organization), the use of the bovine growth hormone polyA signal sequence provides for an enhanced productivity compared to use of the SV40 polyA signal sequence, the addition of the HUT to the bGH PolyA signal sequence results in an increased productivity in vectors containing the hCMV promoter and the vector organization LC(3-5)-HC-SM results in improved expression. For stable pools it is reported that pools generated with vectors containing the hEF1 promoter show an enhanced productivity in batch analysis, clones generated with vectors containing the hEF1 promoter show a reduced number of low producing clones, and clones generated with vectors containing the hEF1 promoter show a higher stability of IgG expression. For single clones it is reported that the vector organization with downstream position of selection marker (LC-HC-SM) has a positive effect on productivity of single clones and that clones generated with vectors containing the bGH polyA signal sequence and the hGT have higher productivities.

The invention provides anti-variant Fc-region antibodies which specifically bind to an antibody that has the mutation P329G or the mutations P329G/L234A/L235A or the mutations I253A/H310A/H435A in the Fc-region, and methods of using the same.

Methods for treating, preventing and reducing the progression of neurodegenerative and neurological diseases, including, without limitation Alzheimer's disease, are provided. The methods of the invention inhibit one or both of TIM-1 and P-selectin function and reduce leukocyte and platelet cell adhesion, activation and interaction with the vascular endothelium and infiltration of leukocytes into the brain.

The invention relates to the use of an anti-P-selectin antibody or binding fragment thereof, suitably crizanlizumab or a binding fragment thereof in the treatment of myelofibrosis (MF). The invention also relates to a pharmaceutical combination comprising a) an anti-P-Selectin antibody and b) at least one further therapeutic agent, preferably ruxolitinib or a pharmaceutically acceptable salt thereof.

Herein is reported an expression vector comprising an antibody light chain expression cassette, an antibody heavy chain expression cassette, and a selection marker expression cassette, wherein the expression cassettes are arranged unidirectional, and wherein the expression cassettes are arranged in the 5 to 3 sequence of antibody heavy chain expression cassette, antibody light chain expression cassette and selection marker expression cassette. Further are reported herein methods for the generation of antibody producing cells and the use of these cells for the recombinant production of antibodies.

The present disclosure relates to compositions and uses thereof for inhibiting epithelial cell proliferation by exposing an epithelial cell to an agent that inhibits P-selectin expression and/or activity.

The present invention relates to the seminal discovery that P-selectin glycoprotein ligand-1 (PSGL-1) modulates the immune system and immune responses. Specifically, the present invention provides PSGL-1 agonists and antagonists which increase the survival of multifunctional T cells and viral clearance. The present invention further provides methods of treating infectious diseases, cancer and immune and inflammatory diseases and disorders using a PSGL-1 modulator.

Described herein are monoclonal antibodies that bind to VSIG-4 including antibodies that block the binding of VSIG-4 to SIGLEC-7, compositions including the monoclonal antibodies, and methods of making and using those antibodies and compositions.

The present disclosure provides, inter alia, anti-peripheral lymph node addressin antibodies and antigen binding fragments thereof. The present disclosure also provides compositions comprising drug-containing polymeric particles that mimic lymphocyte migration in vivo and can specifically deliver immunosuppressive or immunoregulatory drugs to lymphoid tissues and sites of chronic inflammation where T-cell activation and T-cell mediated injury are occurring; such compositions comprise the antibodies or antigen-binding fragments thereof described in the disclosure. The present disclosure also comprises antibody-drug conjugates and compositions comprising the antibody-drug conjugates. Methods of preparing and using these antibodies, antigen-binding fragments thereof, and compositions thereof are also provided.
