Disclosed herein are methods and compositions for generating immunotherapeutic cells (e.g., NK and T cells) with enhanced cytotoxicity and capacity for expansion thereof. The methods and compositions disclosed herein can further be used for enhanced expansion of CAR-modified NK and T cells with increased cytotoxicity.

The present invention relates to a topical pharmaceutical preparation for treating an inflammatory skin condition, preferably a condition associated with ischemia, comprising a supernatant of a physiological solution obtainable by cultivating peripheral blood mononuclear cells (PBMCs) or a subset thereof in a physiological solution free of PBMC-proliferating and PBMC-activating substances for at least 1 h.

The invention relates to a method for the in vitro generation of antigen-specific antibodies or cells producing thereof, said method comprising culturing B cells with an antigen-coated carrier for at least 3 days, wherein said antigen-coated carrier has a size between 0.5 μm and 20 μm, and co-culturing the B cells obtained from step a) with CD4+ T cells for at least 3 days. Thus, high-affinity class-switched immunoglobulins of clinical and diagnostic interest are produced in vitro.

Provided herein, inter alia, are methods and compositions for treating or preventing graft-versus-host disease. The methods include administering to a tissue transplant recipient a composition comprising a donor-derived regulatory T cell.

Methods of expanding tumor infiltrating lymphocytes (TILs), including peripheral blood lymphocytes (PBLs) and marrow infiltrating lymphocytes (MILs), from blood and/or bone marrow of patients with hematological malignancies, such as liquid tumors, including lymphomas and leukemias, and genetic modifications of expanded TILs, PBLs, and MILs to incorporate chimeric antigen receptors, genetically modified T-cell receptors, and other genetic modifications, and uses of such expanded and/or modified TILs, PBLs, and MILs in the treatment of diseases such as cancers and hematological malignancies are disclosed herein.

Production and use of novel therapeutic cells, called T-Vehicles, in the allogeneic Adoptive Cell Therapy setting allows a wide range of therapeutic benefits to accrue with minimal or no risk of GVHD. T-Vehicles are created from donor T cells that are altered to contain therapeutic attributes that do not include their native antigen receptors and can deliver therapeutic benefits irrelevant of their native antigen specificity. T-Vehicles can possess highly restricted native antigen specificity that renders them unable to recognize antigens present on normal cells and incapable of initiating GVHD, making them ideal transport vehicles to deliver various therapeutic attributes in vivo. In essence, production and use of T-Vehicles is a paradigm shift that opens the door to therapeutic application of T cells in ways not previously contemplated, independent of whether or not there is an HLA match between the donor and the recipient.

The present invention relates to a pharmaceutical composition for preventing or treating an autoimmune disease, including stem cells treated with a protein kinase C activator or a culture thereof, and more specifically, the present invention relates to a pharmaceutical composition for preventing or treating an autoimmune disease, which can inhibit the function of B cells and have an excellent prophylactic or therapeutic effect for an autoimmune disease.

In vitro biomimetic models of the neonatal immune system are provided along with methods of using the models in pre-clinical assessment of infant immune cell-mediated and humoral responses to immunogenic stimulation, such as vaccination. The models include one comprising cord blood-derived T follicular helper cells and B cells, and one comprising cord blood-derived dendritic cells and CD4+ T cells. The models can be used, for example, to assess candidate vaccines via analysis of cellular responses to antigen and vaccine exposure.

Provided herein are methods for preparing and characterizing CAR-T cell cultures and preparations.

Described herein are agents and methods for targeting antigen-specific B cells using engineered T cells, such as regulatory T cells or cytotoxic T cells, or bi-specific antibodies. The agents and methods can be used to reduce undesirable immune responses.
