A diagram shows the interplay between innate immune sensing and mechanosensing, highlighting the pathways involved in inflammatory responses. The diagram is divided into two main sections: Innate immune sensing on the left and Mechanosensing on the right. Innate immune sensing includes components like interleukin-1 beta (IL-1 beta), tumor necrosis factor (TNF), pathogen-associated molecular patterns (PAMPs), damage-associated molecular patterns (DAMPs), interleukin-1 receptor (IL-1R), tumor necrosis factor receptor (TNFR), Toll-like receptor (TLR), and NLRP3 inflammasome assembly. These components interact through pathways involving IKB kinase (IKK), nuclear factor kappa B (NF-KB) activation, hypoxia-inducible factor-1 alpha (HIF-1 alpha) stabilization, and the production of pro-inflammatory cytokines such as interleukin-1 beta (IL-1 beta) and interleukin-18 (IL-18), leading to pyroptosis. Mechanosensing involves mechanical forces such as shear stress, stretch or tension, hydrostatic pressure, and tissue stiffness. These forces activate PIEZO1 and transient receptor potential vanilloid 4 (TRPV4) channels, leading to calcium ion flux and subsequent calmodulin binding. This activates calmodulin-dependent kinases (CaM kinases) and calcineurin, which in turn activate nuclear factor of activated T cells (NFAT). The linker of nucleoskeleton and cytoskeleton (LINC) complex and Lamin A/C are involved in nuclear stretch and nuclear pore complex (NPC) widening. The diagram also shows the formation of focal adhesions, focal adhesion kinase (FAK) activation, SRC recruitment, actin polymerization, and actomyosin tension. Hippo signaling involves Yes-associated protein/transcriptional coactivator with PDZ-binding motif (YAP/TAZ) activation and is coupled with the cytoskeleton, affecting migration, cell shape, and phagocytosis. The overall structure illustrates the complex interplay between mechanical cues and immune responses, leading to inflammatory responses.
