摘要： A transgenic mouse is disclosed herein whose somatic and germ cells comprise a disrupted IL-21 receptor gene, the disruption being sufficient to inhibit the binding of IL-21 to an IL-21 receptor, and a disrupted IL-4 gene, the disruption being sufficient to inhibit the production of IL-4 or the binding of IL-4 to the IL-4 receptor. A mouse homozygous for the disrupted IL-21 receptor gene and homozygous for the disrupted IL-4 gene has diminished B cell function. A method is disclosed for altering a B cell activity. The method includes administering a therapeutically effective amount of an agent that interferes with the interaction of IL-21 with an IL-21 receptor, thereby altering the B cell activity. A method is also disclosed for of treating a subject with Job's disorder or atopic disease. A method is also disclosed for treating or preventing an allergic reaction in a subject. A method is also disclosed for treating a subject with an autoimmune or antibody mediated disorder.

摘要： A method is disclosed herein for inducing differentiation of a B cell progenitor into a memory B cells and/or a plasma cell. The method includes contacting a population of cells including a mature B cell or a B cell progenitor with an effective amount of IL-21, and isolating memory B cells or plasma cells. In one embodiment, the B cell progenitor is an immature B cell. A method is also disclosed for enhancing an immune response. The method includes contacting a population of cells including a B cell progenitor with an effective amount of IL-21, and isolating memory B cells or plasma cells. The memory B cells and/or the plasma cell are then introduced into the subject to enhance the immune response. A method is also disclosed for treating a subject with a condition comprising a specific deficiency of at least one of memory B cells and plasma cells. A method is disclosed for identifying an agent with a physiological effect on one or more of a memory B cell and a plasma cell differentiation.

摘要： Disclosed is a method for treating tissue necrosis (loss) in an animal. Tissue necrosis is treated by providing the subject with an anti-adhesion cell agent capable of binding an ICAM-1 antigen, a CD18 antigen, an L-selectin agent, a CD44 antigen, a P-selectin antigen, a VCAM-1 antigen, an ICAM-2 antigen, or a fragment thereof. Also provided is a method for preventing thermal-related tissue loss or necrosis, particularly the thermal injury and progressive tissue necrosis which results from a burn injury. Thermal-related tissue injury surrounding a thermal injury site is inhibited or prevented by providing an animal with an anti-adhesion agent, such as an anti-CD18 antibody, an anti-ICAM-1 antibody, or a mixture or fragment thereof. A method for inhibiting/preventing scarring attendant healing of a thermal injury is also disclosed.
