Estimating the term…
Vaccine composition containing IL-15 for active immunization to treatment diseases related to over-expression of this cytokine. The technical aim pursued in this invention is to inhibit IL-15 activity through development of a therapeutic vaccine which elicits IL-15 neutralizing antibodies in the immunized host. IL-15 can be presented in this vaccine composition either alone or coupled to a carrier such as the P64k protein with a vaccine adjuvant such as Aluminum hydroxide. Besides, this invention is related to the use of this vaccine for treatment of Rheumatoid arthritis and other IL-15 over-expressing related diseases, and leukemia, where this cytokine acts as a growth factor.
A method for generating a neutralizing antibody response against autologous IL-15 in a primate, wherein said method comprises administering to said primate a composition comprising human IL-15 and aluminum hydroxide, wherein the IL-15 is an antigen and wherein said IL-15 antigen generates neutralizing self-antibodies against IL-15.
