Cellular bucket lista
Death trigger | Death pathway | Bucket lists | Death-delaying mechanism | Living duration | Consequence of missing execution | Refs | |
---|---|---|---|---|---|---|---|
| |||||||
Neutrophils | Intracellular rod, needle, flagellin | NAIP/NLRC4/Caspase-1/GSDMD | IL-1β processing/release, phagocytosis, ROS production | ND | 5 hours and more | Reduced bacterial killing | [55–57] |
Neutrophils | Intracellular LPS, PMA | Caspase-11/GSDMD, Neutrophil Elastase/GSDMD | NET formation pathway | ND | 30–60 min | Failure to form NETs and reduced bacterial killing | [63,64] |
Macrophages | Activators for NLRP1, NLRP3, NLRC4, Aim2, Pyrin | Caspase-1/GSDMD | IL-1β processing | ESCRT repair? | 30–60 min | Failure to release mature IL-1β | |
Macrophages DCs | oxPAPCs bacterial peptidoglycan fragments, and mutant Staphylococcus aureus | CD14/Caspase-11/NLRP3/Caspase-1/GSDMD | Both macrophages and DCs; IL-1β processing/release, DCs only; Antigen presentation | ND | Macroph ages; 16 hours or more DCs; A few days | Failure to release mature IL-1β, Less antigen-specific T cell responses | [3, 66–68] |
IECs | Intracellular rod, needle, flagellin | NAIP/NLRC4/Caspase-1/GSDMD | Cell extrusion pathway; | Caspase-7/ASM-mem brane repair | 30–60 min | Failure to extrude IECs, More tissue damage | [4] |
Hepatocytes | NK/CTL attack | Perforin/granzymes/Caspase-3 | Apoptosis-rel ated bacterial clearance | Caspase-7/ASM-mem brane repair | ND | Failure to clear intracellular pathogens | [4] |
