Recent advance in autoimmunity research reveals that the innate immune system is able to recognize self-targets and initiate inflammatory response in a similar way as with pathogens. This is what anti-CTLA-4 blockage has done. Accordingly, alterations in cell morphology are recognized by the innate immune system resulting in an acute inflammatory response (Carroll and Holers,2005).
"Our immune system is an impressive piece of biological machinery using
specialized cells and soluble mediators to protect us from foreign substances such as bacteria, viruses and cancer cells. The immune system is historically divided into two parts, the innate and the adaptive immune systems. Although working together for effective protection these two systems differ from each other in many respects. The innate immune response has componentsrecognizing characteristic features that are common within groups of microbes and cannot distinguish the fine differences between foreign substances. The principal components of innate immunity are physical and chemical barriers, phagocytic cells, blood proteins and cytokines which all react to repeated infections in essentially the same way in which they first responded. The defining characteristics of adaptive or specific immunity are exquisite specificity and the ability to remember and respond more vigorously
to repeated exposures to the same pathogen. The key components of
the adaptive system are B- and T lymphocytes, which can differentiate to
effector or memory cells after stimulation by foreign molecules known as
antigens (Ags)."

Early Immunostimulatory Effects of IgE- and IgG Antibodies
author FREDRIK HJELM
With this in mind, I had an Innate immune response when the CTLA-4 engage the B7 receptor. The response was an inflamatory response on day 15.
Base on the Innate immune response froma natural antibody. It takes about two week to generate a response.This response I posulate as the danger signal needed for T-cells to begin their frontal attack on the foreign invaders (The Cancer Cells).
I am in contact with Kirkwood and Medarex trying to convince them of my theory. I has been a hard sell.
response:Fine theory but just theory that has never been tested in relevant clinical setting…
