In their Review, Julien Morival, Anna Hazelwood and Jan Lammerding @lammerdinglab.bsky.social discuss new insights and technological advances in understanding nuclear mechanotransduction. journals.biologists.com/jcs/article/...
Cartoon showing key mechanotransduction signalling pathways to the nucleus. Mechanosensitive ion channels at the plasma and nuclear membranes allow Ca2+ entry into the cytoplasm and nucleus, activating downstream signalling pathways. NE stretching opens NPCs, facilitating entry of transcription factors (TF) and transcriptional coregulators (TCR) that alter gene expression. Additionally, NE stretching activates Ca2+ channels in the ER, promoting Ca2+ entry into the nucleus. Stretch-induced activation of cytosolic phospholipase A2 (cPLA2) further drives the arachidonic acid (AA) pathway, leading to gene expression changes.

Delighted to share our latest in @discovimmunol.bsky.social with @kathelse.bsky.social Holly Shiels, Iris Mair & Susanne Shultz. Climate change, pollution and changing land use impact immune function, driving chronic inflammatory disease and create exposure to infections (new & old). 🧪 #Immunosky
Ecoimmunology. Fundamental discovery lab-based immunology typically focuses on defined model systems—(in vitro or in vivo models such as mice or ex vivo tissues) to understand immune programming in the context of biological processes, health, and disease. In contrast, disease ecology focuses on the role of the environment and considers population dynamics and individual variation. Whilst there is some limited overlap in disciplines, the area of ecoimmunology aims to bridge these gaps and takes a more holistic approach to understanding what shapes the immune system and thereby health.
