A method for treating a patient comprising: (a) providing a composition comprising a population of T cells expressing both a chimeric antigen receptor (CAR) and a T cell receptor specific for a cytomegalovirus (CMV) antigen; (b) administering the composition to the patient; and (c) administering to the patient a viral vector encoding: (i) CMV pp65 and (ii) a fusion protein comprising exon 4 of CMV protein IE1 (e4) and exon 5 of CMV protein 1E2 (e5) either prior to or subsequent to administering the composition comprising a population of T cells to the patient is described.

Provided are multi-specific antigen binding molecules, including bispecific antibodies, that bind to CD3 and an HIV antigen, including HIV envelope protein gp120. Also provided are methods of using such antigen binding molecules to treat or prevent HIV infection.

Provided herein are recombinant nucleic acids encoding T cell receptor (TCR) fusion proteins (TFPs), modified human immune cells expressing the encoded molecules, and methods of use thereof for the treatment of diseases, including cancer.

The present invention relates to a chimeric antigen receptor comprising a c-Met binding domain, and a use thereof. The chimeric antigen receptor comprising a c-Met domain, of the present invention, can be effectively usable as an agent for treating various diseases associated with c-Met expression.

Provided herein are novel blocking chimeric antigen receptors (“bCARs”) and immune cells (e.g., effector and regulatory immune cells) that express such bCARs. Such blocking CARs prevent undesired activation of the immune cells, particularly undesired activation of the immune cells against normal tissue in therapeutic applications. Thus, such bCARs advantageously allow for selective immune cell activation only upon interaction with specific target cells (e.g., tumor cell).

The present disclosure provides adoptive T cell therapies that have improved DARIC architectures for targeting tumor antigens and recruiting TCR signaling complexes for treating, preventing, or ameliorating at least one symptom of a cancer, infectious disease, autoimmune disease, inflammatory disease, and immunodeficiency, or condition associated therewith.

The invention provides an isolated or purified T-cell receptor (TCR) having antigenic specificity for MHC Class II-restricted MAGE-A3. The invention further provides related polypeptides and proteins, as well as related nucleic acids, recombinant expression vectors, host cells, and populations of cells. Further provided by the invention are antibodies, or an antigen binding portion thereof, and pharmaceutical compositions relating to the TCRs of the invention. Methods of detecting the presence of cancer in a host and methods of treating or preventing cancer in a mammal are further provided by the invention.

The present disclosure features, at least in part, methods for conserving cell function, e.g., immune cell function, e.g., after one or more cycles of freezing and/or thawing the nucleated cell. In embodiments, the methods comprise contacting an immune cell with a protein nanoparticle comprising an IL-15 complex.

The present disclosure provides improved CD33 targeting polypeptides and compositions for adoptive T cell therapies for treating, preventing, or ameliorating at least one symptom of a cancer, infectious disease, autoimmune disease, inflammatory disease, and immunodeficiency, or condition associated therewith.

The present disclosure provides improved CLL-1 targeting polypeptides and compositions for adoptive T cell therapies for treating, preventing, or ameliorating at least one symptom of a cancer, infectious disease, autoimmune disease, inflammatory disease, and immunodeficiency, or condition associated therewith.
