The present invention is directed to the field of immunotherapy. Specifically, the invention provides compositions and methods for improved T cell modulation ex vivo and in vivo and for the treatment of cancer and other pathologies. More specifically, embodiments of the invention are directed to the use of soluble NTB-A polypeptides or agonists thereof for the treatment of cancer patients, for preventing and treating cytopenia in susceptible patients, and for the ex vivo preparation of improved cell compositions.

The addition of a selective, fast-acting, short half-life CDK 4/6 inhibitor in a very specific dosage regimen to the combination of chemotherapy with a checkpoint inhibitor provides superior results in the treatment of a tumor or cancer. The unexpected discovery is that the short pulsatile specifically-timed administration of a selective, fast-acting, short half-life CDK 4/6 inhibitor during administration of the chemotherapy portion of the triple combination therapy has a profound effect on the immune cells in the cancer microenvironment.

Disclosed are means, methods and compositions of matter useful for treatment of lung inflammation associated with viral and bacterial infections, as well as with systemic inflammation, through administration of umbilical cord blood derived plasma-based compositions. In one embodiment the invention teaches administration of umbilical cord blood plasma together with pterostilbene, and/or sulforaphane, and/or thymoquinone, and/or Epigallocatechin gallate (EGCG) and/or n-acetylcysteine in an aerosolized manner to patients suffering from COVID-19 associated pulmonary deficiencies. In another embodiment, umbilical cord blood plasma is administered with immune stimulatory agents in order to concurrently inhibit propagation of viral load in the lung while suppressing pulmonary deficiencies.

The present invention relates to a method for treating anemia using a long-acting EPO formulation, and more specifically, a method for treating patients with anemia by confirmation of safe, long-acting, and optimal effective dosage and usage in administering a fusion polypeptide which comprises an EPO and an immunoglobulin hybrid Fc to patients with anemia. The method of administering the fusion polypeptide employs an appropriate dosage and usage which not only shows an excellent long-acting property compared to the existing EPO products but also minimizes cardiovascular side effects that may occur due to a rapid increase in hemoglobin level, which is an effect of anemia treatment.

The invention provides compositions and methods for treating diseases associated with expression of CD20 or CD22. The invention also relates to chimeric antigen receptor (CAR) specific to CD20 or CD22, vectors encoding the same, and recombinant T or natural killer (NK) cells comprising the CD20 CAR or CD22 CAR. The invention also includes methods of administering a genetically modified T cell or NK cell expressing a CAR that comprises a CD20 or CD22 binding domain.

A use of a CD200 extracellular domain protein or a fusion protein formed from a CD200 extracellular domain protein and an Fc fragment in preparing a drug for treating psoriasis is disclosed.

The present disclosure provides T-cell modulatory multimeric polypeptides that comprise an immunomodulatory polypeptide, an epitope-presenting peptide, and class I MHC polypeptides. A T-cell modulatory multimeric polypeptide is useful for modulating the activity of a T cell, and for modulating an immune response in an individual.

Compounds of formulae (I) and (II), compositions, and methods for use in inhibiting the E3 enzyme Cbl-b in the ubiquitin proteasome pathway are disclosed. The compounds, compositions, and methods can be used to modulate the immune system, to treat diseases amenable to immune system modulation, and for treatment of cells in vivo, in vitro, or ex vivo.

Provided herein are agents, such as antibodies, antibody-drug conjugates, or chimeric antigen receptors, that target EphA10. Methods of treating cancer are provided, comprising administering to a patient in need thereof an effective amount of an EphA10-targeting agent. The patient may be selected for treatment if the cancer expresses an increased level of EphA10.
