Abstract

The present invention pertains to a method for non-specifically enhancing the immune system response of a mammal to an antigen which comprises the steps of (a) withdrawing leukocyte containing material from the mammal, (b) treating the withdrawn leukocytes in a manner to alter the cells, and (c) returning the treated leukocytes to the mammal. In one embodiment, the method for non-specifically enhancing the immune system response of a mammal is carried out in conjunction with artificially contacting the mammal'"'"'s immune system with an antigen for a suitable period of time to stimulate the immune system. In another embodiment, the mammal'"'"'s immune system is naturally exposed to the antigen prior to the non-specific enhancement of the immune system. In yet another embodiment, the invention is directed at a method for preparing an autologous non-specific leukocyte adjuvant.

Claims

1. A method for non-specifically enhancing the immune system response of an immunodeficient mammal to an antigen, the method comprising the steps of:

a) determining if the mammal'"'"'s helper/inducer T cell count is at least 150 per cubic milliliter of blood and, if so, conducting the following steps (b)-(d);

b) withdrawing leukocyte containing material from the mammal;

c) treating the withdrawn leukocytes in a manner to alter the cells; and

d) returning the treated leukocytes to the mammal.

2. The method according to claim 1, wherein the mammal is a human.

3. The method according to claim 1, wherein the leukocyte containing material is selected from the group consisting of blood, lymph fluid, bone marrow, and lymphatic organ tissue.

4. The method according to claim 1, wherein the treatment of the leukocytes is by irradiating the leukocytes with ultraviolet radiation in the presence of a photoactivatable agent.
