IL-1beta (Interleukin-1 Beta)

Metal Connection#

Signal 1 (priming): Metals (Cadmium, Lead, Nickel, Arsenic) activate NF-kB → pro-IL-1β transcription.^{[1]Toxic Mechanisms of Five Heavy Metals: Mercury, Lead, Chromium, Cadmium, and ArsenicBalali-Mood M, Naseri K, Tahergorabi Z et al. · 2021Open reference 1 ↓} Signal 2 (activation): Metal-generated ROS, potassium efflux, and lysosomal disruption (from metal nanoparticle endocytosis) activate NLRP3 → caspase-1 → mature IL-1β release.

Metals uniquely provide BOTH signals, making them potent inflammasome activators.

Microbiome Context#

C. albicans + P. gingivalis: Mixed biofilm triggered 25-fold increase in IL-1β from THP-1 macrophages (vs. 4-fold lower with bacteria alone), likely through different release mechanisms (microvesicle-protected from gingipain degradation).^{[2]Bartnicka et al. 2020 — Candida albicans Shields the Periodontal Killer Porphyromonas gingivalis from Recognition by the Host Immune System and Supports the Bacterial Infection of Gingival TissueDominika Bartnicka, Miriam Gonzalez-Gonzalez, Joanna Sykut et al. · 2020Open reference 2 ↓}
