Resumo: | Protein folding disorders of aging like Alzheimer&amp;#x27;s and Parkinson&amp;#x27;s diseases currently present intractable medical challenges. &amp;#x27;Small molecule&amp;#x27; interventions - drug treatments - often have, at best, palliative impact, failing to alter disease course. The design of individual or population level interventions will likely require a deeper understanding of protein folding and its regulation than currently provided by contemporary &amp;#x27;physics&amp;#x27; or culture-bound medical magic bullet models. Here, a topological rate distortion analysis is applied to the problem of protein folding and regulation that is similar in spirit to Tlusty&amp;#x27;s (2010a) elegant exploration of the genetic code. The formalism produces large-scale, quasi-equilibrium &amp;#x27;resilience&amp;#x27; states representing normal and pathological protein folding regulation under a cellular-level cognitive paradigm similar to that proposed by Atlan and Cohen (1998) for the immune system. Generalization to long times produces diffusion models of protein folding disorders in which epigenetic or life history factors determine the rate of onset of regulatory failure, in essence, a premature aging driven by familiar synergisms between disjunctions of resource allocation and need in the context of socially or physiologically toxic exposures and chronic powerlessness at individual and group scales.
