After sleep and feeding shifts, does faster healing prolong infection vulnerability, and does timed treatment protect transplants better than continuous suppression?

Accelerated resolution creates antimicrobial vulnerability by causing macrophages to destroy viable, actively bactericidal neutrophils before their defensive work is complete. Oxidative activation exposes phosphatidylserine, making the strongest defenders preferential engulfment targets. Shifted sleep and feeding bring heightened macrophage engulfment into coincidence with this activation peak. The causal substrate is activation-dependent membrane labeling followed by engulfment-induced death, rather than suppressive programming of surviving cells. Resolution support timed outside this overlap should preserve both containment and graft function; continuous support repeatedly removes the cells most needed for containment. Preventing this inappropriate live-cell removal would stabilize SPV_10.

Matched cells protected from contact will remain viable and continue killing. Selectively protecting viable neutrophils from engulfment, while preserving apoptotic-corpse clearance, will abolish the excess dissemination caused by resolution acceleration without forfeiting its graft-protective effect. Merely redirecting neutrophil migration will not rescue containment once these cells reach the interface and are removed. Finding that engulfed neutrophils were already irreversibly dying, or that viable-cell protection fails despite verified target engagement, would reject this mechanism.

The defense gap arises because resolution changes the rule by which viable neutrophils choose among simultaneous tissue signals. Residual sterile interface signals win recruitment decisions over adjacent microbial signals despite intact migration capacity, adequate leukocyte availability and preserved bacterial killing. Shifted rhythms alter receptor-specific signaling weights, allowing continuous resolution support to maintain an inappropriate ranking during pathogen exposure. Phase-targeted support succeeds when microbial signals retain priority. The causal substrate is the intracellular weighting of competing receptor signals, not insufficient defensive resources. Restoring the correct ranking would stabilize SPV_10.

Independently measured signaling weights will predict a crossover in destination as the cue ratio changes. Selectively reducing the dominant sterile cue or correcting its receptor weighting will restore containment without changing neutrophil survival, efferocytosis or per-cell bacterial killing. A generalized defect in isolated-cue responses, absence of a competitive ranking change, or failure of cue correction despite restored directionality would reject this explanation.

Accelerated efferocytosis creates vulnerability because viable pathogens enclosed in dying cells or membrane fragments gain access to new permissive host cells through the resolution machinery. Local inflammation and interface injury decline while the number of successful intracellular infection transfers increases. Shifted schedules increase overlap between infected-cargo availability and enhanced engulfment. Phase-targeted resolution therefore helps only when delivered after viable cargo has been eliminated; host-clock phase alone cannot guarantee safety. The propagating substrate is infectious membrane-enclosed cargo, and preventing its uptake-mediated amplification would stabilize SPV_10.

Rendering cargo noninfectious while preserving its membrane recognition and uptake will remove the adverse effect of accelerated resolution. Correcting chemotactic ranking or protecting uninfected viable neutrophils will not remove that transfer-dependent excess. The apparent optimal treatment phase will move when infected-cargo availability is shifted without shifting the host clock. Absence of productive cargo-mediated transfer rejects this mechanism even if infection still worsens.

Resolution redirects living neutrophils toward sterile tissue signals predicts instead: Neutrophils isolated at the vulnerable phase will respond normally to either sterile or microbial cues presented alone but choose the sterile source when the same cues compete.
