The present invention relates to a macrophage, genetically engineered to overexpress Interleukin-10 (IL-10) or IL-10 in combination with Matrix Metallopeptidase 9 (MMP9). Such a macrophage may be for use in treatment of an inflammatory condition in a subject such as inflammatory organ damage. The inflammatory condition may be acute or chronic and may involve a fibrotic element.

The present invention provides a composition comprising dendritic cells loaded with hHsp60sp, which dendritic cells are from a subject and have been fixed with paraformaldehyde (PFA). The subject may suffer from an autoimmune disease. Also provided are a method for preparing the composition; recombinant human cells comprising a heterologous gene encoding a fusion protein of HLA-E and hHsp60sp or B7sp, and expressing the fusion protein on the surface of the cells; a method for determining a percentage of maximum inhibition of testing the function of the HLA-E restricted CD8+ Treg cells from a subject, determining whether HLA-E restricted CD8+ Treg cells freshly isolated from a subject are defective, or determining whether defective HLA-E restricted CD8+ Treg cells from a subject are correctable; and a method for correcting defective HLA-E restricted CD8+ Treg cells, treating type 1 diabetes (T1D), or treating multiple sclerosis (MS).

The present invention concerns methods of generating CTLs that are able to target at least one antigen from two or more viruses. The method includes exposing mixtures of peptides for different antigens to the same plurality of PBMCs and, at least in certain aspects, expanding the cells in the presence of IL4 and IL7.

The present invention provides modified monocytes, modified macrophages, pharmaceutical compositions comprising the modified monocytes or modified macrophages described herein and at least one pharmaceutically acceptable carrier or excipient. Uses of the modified monocytes or the modified macrophages for the treatment of musculoskeletal diseases and inducing cartilage formation are provided. Also disclosed herein are in vitro culture methods for generating the modified macrophages.

The present invention provides: a novel method for the production of truly fully human monoclonal antibodies against specific antigens of our choice using isolated human blood cells. These antigens may include but are not limited to peptide sequences found in c-met and TMX2 proteins; an antibody specific for c-met protein produced with said method; an antibody specific for TMX2 protein produced with said method; and a new means and method for the diagnosis, prevention and/or cancer treatment by means of the aforementioned antibodies.

Disclosed are a method for producing a cell population in which regulatory T cells have proliferated, including (1) culturing a cell population containing CD4.sup.+ T cells derived from pluripotent stem cells in the presence of IL-4 and a TGF-R agonist, a cell population containing regulatory T cells obtained according to the method, and a medicine containing the cell population containing regulatory T cells.

The present disclosure belongs to the field of biotechnology, and specifically relates to a preparation method for an adenovirus p53 (Ad-p53)-loaded dendritic cell (DC) vaccine. The present disclosure includes steps of peripheral blood collection and peripheral blood mononuclear cell (PBMC) separation, PBMC sorting, DC activation, Ad-P53-transfected DC and DC vaccine preparation. P53 can be expressed on a surface of DC as a tumor-associated antigen (TAA) through DC purification, specific multiplicity of infection (MOI) and infection modes, and the Ad-P53-transfected DC has obvious antigen presentation effect, which can be used as a vaccine to activate T cells to kill tumors.
