Other - Theoretical model of the immune system
Examined through the multiple and diverse specific lines of research, our understanding of the immune system is formed by an attempt to reconcile several fragments of very narrow observations. As much as this approach has been useful, it has also caused harm because, by being very specific, it tries to assemble the puzzle not by trying the pieces together, but by studying them one by one, making it very difficult to grasp the big picture: what is the role of the immune system? Where does it fit in the puzzle of Life? And what is the driving evolutionary directive that commands it.
Analyzing this question through the perspective of the one characteristic every living organism has in common: being alive, and that life is subject to the same physical laws that command the whole universe, we make a case for redefining the role commonly assigned for the immune system (to protect the organism against foreign invasions), to something more comprehensive that brings several implications for research and therapeutics: safeguard the energy accumulated by an organism, so it can use it for its own interests and not someone else's, or, in essence, keeping that organism's ΔG negative, which represents the basic definition of survival or extinction.
This new context allows for a new, wider and more logical contextualization of life and immunity and, we think, a useful and evolving one.
