    摘要: A method for producing a clone of an immortalized human B memory lymphocyte, comprising the step of transforming human B memory lymphocytes using Epstein Barr virus (EBV) in the presence of a polyclonal B cell activator. The method is particularly useful in a method for producing a clone of an immortalized human B memory lymphocyte capable of producing a human monoclonal antibody with a desired antigen specificity, comprising the steps of: (i) selecting and isolating a human memory B lymphocyte subpopulation; (ii) transforming the subpopulation with Epstein Ban virus (EBV) in the presence of a polyclonal B cell activator; (iii) screening the culture supernatant for antigen specificity; and (iv) isolating an immortalized human B memory lymphocyte clone capable of producing a human monoclonal antibody having the desired antigen specificity.

    摘要: Regulatory B cells (tBreg) are disclosed herein. These regulatory B cells express CD25 (CD25+) a pan B cell marker such as B220 (B220+), and also express CD19 (CD19+). These regulatory B cells suppress resting and activated T cells in cell contact-dependent manner. Methods for generating these regulatory B cells are also disclosed herein, as are methods for using these regulatory B cells to produce regulatory T cells (Treg). In some embodiments, methods for treating an immune-mediated disorder, such as an autoimmune disease, transplant rejection, graft-versus-host disease or inflammation, are disclosed. These methods include increasing regulatory B cell number or activity and/or by administering autologous regulatory B cells. Methods for treating cancer are also disclosed herein. These methods include decreasing regulatory B cell activity and/or number.
