Inflammatory cell rupture
Ordinary turnover is quiet — the cell folds itself away and is cleared. This kind ruptures instead. That is why the illness amplifies itself: each rupture recruits more inflammation, which drives the next one.
In depth
Inflammatory cell rupture — a cell that ruptures instead of folding away quietly, spilling its contents and inflaming the tissue around it.
What drives it
Inflammatory protease increases it.
PMC6505044 — A different kind of dying. Ordinary programmed cell death is quiet and tidy — the cell folds itself away. This one bursts, spilling its contents and inflaming everything around it. And the trigger is named: 'in experimental CVB3-induced myocarditis, inflammasome activation and subsequent pyroptosis seem to be mediated by cathepsin B' (ScienceDirect Topics — Coxsackievirus B3 overview (citing Toldo et al. 2014; Wang, Gao & Xiong 2014; Wang et al. 2018)). ⇒ that is why this illness amplifies itself: every cell that dies this way recruits more inflammation to kill the next one.

Lysosomal protease increases it.
PMC5809100 — A different kind of dying. Ordinary programmed cell death is quiet and tidy — the cell folds itself away. This one bursts, spilling its contents and inflaming everything around it. And the trigger is named: 'in experimental CVB3-induced myocarditis, inflammasome activation and subsequent pyroptosis seem to be mediated by cathepsin B' (ScienceDirect Topics — Coxsackievirus B3 overview (citing Toldo et al. 2014; Wang, Gao & Xiong 2014; Wang et al. 2018)). ⇒ that is why this illness amplifies itself: every cell that dies this way recruits more inflammation to kill the next one.

The Handbrake the Virus Releases reduces it.
And this is the cruellest trick in the whole MAP: the virus releases the brake on the cell's self-destruct. 'both 2A and 3C are required for cleavage of CARD8, which normally functions to inhibit activation of CASP1 and pyroptosis' (pmc10178405 · PMID 37175422 — Role of Coxsackievirus b3-Induced Immune Responses in the Transition from Myocarditis to Dilated Cardiomyopathy and Heart Failure). ⇒ CARD8 is a handbrake. Cutting it lets the inflammatory cell-death machinery run. the bursting cell death is not an accident of the infection — the virus actively unlocks it. PMID 37175422
