You have had the same thing for three weeks. Not serious, not dramatic, just the low-grade immune failure of a body that cannot quite clear what it should be clearing. The doctor says it is a virus, it will pass, rest and fluids. You rest when you can. It does not pass. And you notice, if you attend to the timing, that the flare tends to arrive in the weeks after the sustained performance: the long stretch of managing and accommodating and presenting the manageable version of yourself. The body held the performance and then, when the performance stopped, could not hold anything else. This is not coincidence. The immune system and the stress system are not separate systems. The cortisol that the monitoring program requires does not leave the immune system alone. It adjusts the immune system to serve the monitoring program’s priorities.
Irun Cohen’s work on the immune system as a cognitive system represents one of the most underappreciated contributions to the understanding of identity in contemporary science. Cohen argues, across decades of immunological research, that the immune system is not a defense system but a cognitive system: it maintains a continuously updated model of what the self is, learns from experience, has memory, and makes decisions on the basis of pattern recognition that exceeds what the central nervous system performs. The immune system’s model of the self is built from the molecular patterns of this organism’s proteins, updated constantly as the organism develops and changes, capable of tolerating self-derived material even when it arrives in configurations the system has not previously encountered. The immune system, in Cohen’s account, is a second mind.
The person running the not-choosing loop has a chronically dysregulated immune system. The dysregulation has a dimension that the inflammatory account does not fully capture. The immune system that is chronically activated, maintaining the heightened surveillance the loop requires, is an immune system whose distinction-making function is operating under stress. The research on chronic stress and autoimmune disease — the dramatically elevated rates of rheumatoid arthritis, lupus, multiple sclerosis, thyroid dysfunction, and inflammatory bowel disease in people with early adverse relational experience and chronic stress profiles — points toward something more specific than simple immune suppression. Autoimmunity is not immune suppression. It is immune misdirection: the immune system attacking self-derived material, failing to maintain the distinction between self and not-self under chronic stress conditions.
The gut microbiome adds another dimension. The enteric immune system, which comprises approximately seventy percent of the body’s total immune cells, is in constant negotiation with the microbiome: determining which of the trillions of microbial inhabitants are to be tolerated, which are to be mobilized against, and where the boundary of the self ends and the microbial community begins. The cortisol dysregulation of the loop alters the enteric immune system’s negotiation with the microbiome, shifting the microbiome toward compositions associated with higher inflammatory signaling, which feeds back on the enteric nervous system and the brain through the vagus nerve, which further dysregulates the stress response. The immune system, the gut, and the chronic stress of the loop are in a three-way reinforcing relationship.
The ACE study’s finding that adverse childhood experiences predict adult autoimmune disease across multiple diagnostic categories is not a psychological finding about psychological outcomes. It is a biological finding about biological outcomes. The self that was reduced in the first room was reduced not only psychologically but immunologically. The immune system was calibrated, like the nervous system, to conditions that no longer exist. The research does not suggest that healing the psychological wound will cure an established autoimmune condition. It suggests that the conditions that produced the psychological wound also produced the immune dysregulation, and that addressing the conditions has measurable downstream effects on the immune system’s functioning.
What the immune system has been defending, through all of it, is the biological self that the loop has been underrepresenting. The immune system does not know about the first room. It does not have a working model of relational safety. It has a model of what this organism is at the molecular level, and it defends that model with a consistency and a precision that the psychological self has not been permitted. The immune system has no interest in the manageable version of the self. It defends the actual organism: the full biological entity, the unreduced genetic inheritance, the specific and irreplaceable cellular architecture of this particular person. When the management reduces, the immune system does not have to change its allegiance. It was always defending the full self. The conditions are finally beginning to match what the immune system has been maintaining all along.
