Theoretical Validation of Extracellular Vesicles (EVs) within the ISHEA-TACC Framework

1. Introduction

The ISHEA-TACC framework postulates that the interaction between FOXP2/FOXP3, mitochondrial ATP, and cortisol determines systemic resilience (+R) or propagation of dysfunction (–R) in neuronal and peripheral systems. Extracellular vesicles (EVs) act as intercellular communication vehicles, materializing the TACC flow and amplifying the influence of the donor cell on its environment.

Main hypothesis: "Cells with disrupted TACC flow release EVs that propagate dysfunction (+R → –R), while cells with harmonious TACC release EVs promoting resilience."

ISHEA-TACC Framework: Integrating Extracellular Vesicles (EVs) in Systemic Resilience

1. Introduction

Extracellular vesicles (EVs) now emerge as a key mechanism of intercellular communication, materializing TACC flow across cells, tissues, and organs.

Core hypothesis: "Cells with disrupted TACC release EVs propagating dysfunction (+R → –R), while cells with harmonious TACC release EVs promoting resilience."

2. EVs in the ISHEA-TACC Context

EVs carry critical cargo: DNA fragments, mRNA, miRNA, proteins (including transcription factors like FOXP2), ATP, NAD⁺, and lipids. They act as messengers of cellular state, reflecting energy, transcriptional, and hormonal status.
