Recombinant herpes simplex virus having expression cassette expressing fused protein of cancer cell-targeting domain and extracellular domain of HVEM and use thereof

The present invention relates to a recombinant herpes simplex virus (HSV) containing an expression cassette capable of expressing a fused protein of a cancer-cell-targeting domain and an extracellular domain of HVEM and the use thereof. When the recombinant HSV infects and enters target cells, which are cancer cells, HSV proliferates, and an adapter, which is the fused protein, is expressed in the cells and is released to the outside of the cells along with the proliferated HSV virion upon cell lysis, or is released even before the virion is released due to cell lysis when the adapter contains a leader sequence, and the fused protein released to the outside of the cells acts to induce the HSV virion to infect surrounding cancer cells expressing a target molecule recognized by the cancer-cell-targeting domain or to increase the infection efficiency thereof.

Chimeric antigen receptors

A chimeric antigen receptor (CAR) comprising an extracellular spacer which comprises at least part of the extracellular domain of human low affinity nerve growth factor (LNGFR) or a derivative thereof.

IMMUNE CELL COMPOSITIONS AND METHODS OF USE

Disclosed herein are cells that are immune cells or precursor cells thereof, which cells recombinantly express a chimeric antigen receptor (CAR), and a dominant negative form of an inhibitor of a cell-mediated immune response of the immune cell, wherein the CAR binds to a cancer antigen. Also disclosed herein are T cells that recognize and are sensitized to a cancer antigen, which T cells recombinantly express a dominant negative form of an inhibitor of a T cell-mediated immune response. Additionally provided are methods of using such cells to treat cancer in a subject in need thereof.

Compositions and methods for immunotherapy

The present invention provides immunoresponsive cells, including T cells, cytotoxic T cells, regulatory T cells, and Natural Killer (NK) cells, expressing an antigen recognizing receptor and an inhibitory chimeric antigen receptor (iCAR). Methods of using the immunoresponsive cell include those for the treatment of neoplasia and other pathologies where an increase in an antigen-specific immune response is desired.

ADJUVANT EFFECT OF THE TLR1/2 AGONIST DIPROVOCIM SYNERGIZES WITH CHECKPOINT-INHIBITING ANTIBODIES TO ELIMINATE DISEASE
20210315992 · 2021-10-14 ·

A potent human and mouse Toll-like receptor (TLR)1/TLR2 agonist was identified and optimized, Diprovocim, which exhibited an EC.sub.50 of 110 pM in human THP-1 cells and 1.3 nM in primary mouse peritoneal macrophages. In mice, Diprovocim-adjuvanted ovalbumin immunization promoted antigen-specific humoral and CTL responses, and synergized with anti-PD-L1 treatment to inhibit tumor growth, generating long-term anti-tumor memory, curing or prolonging survival of mice engrafted with the murine melanoma B16-OVA. Diprovocim induced greater frequencies of tumor infiltrating leukocytes than alum, of which CD8 T cells were necessary for the antitumor effect of immunization plus anti-PD-L1 treatment.
