Intracellular versus extracellular inhibition of calpain I causes differential effects on pain in a rat model of joint inflammation

Molecular Pain, 2021
Calpain I is a calcium-dependent cysteine protease which has dual effects on tissue inflammation depending on its cellular location. Intracellularly, calpain I has pro-inflammatory properties but becomes anti-inflammatory when exteriorised into the ...

Interleukin‐1α Mediates Pancreatic Fibroblast Activation, Regulates Immune Cell Recruitment and Fibrosis in Acute and Chronic Pancreatitis

Advanced Science, EarlyView.
During pancreatitis, IL‐1α is released from necrotic acinar cells. In response to IL‐1α, pancreatic fibroblasts release chemokines and cytokines that regulate the recruitment of immune cells to the damaged organ. Furthermore, IL‐1α primes fibroblasts, resulting in increased tissue fibrosis during chronic pancreatitis.

Anti-GD1a antibodies activate complement and calpain to injure distal motor nodes of Ranvier in mice [PDF]

, 2010
The motor axonal variant of Guillain-Barré syndrome is associated with anti-GD1a immunoglobulin antibodies, which are believed to be the pathogenic factor. In previous studies we have demonstrated the motor terminal to be a vulnerable site.

Spatio-temporal regulation of calpain activity after experimental myocardial infarction in vivo

Biochemistry and Biophysics Reports, 2021
Background: Calpains are calcium activated cysteine proteases that play a pivotal role in the pathophysiology of cardiac remodeling. Methods: Here, we performed left anterior descending coronary artery ligation in rats as a model for ischemic systolic ...

Tumor Mechanical Remodeling via Bidirectional Calcium Redistribution Enables Deep Photothermal‐Immunotherapy

Advanced Science, EarlyView.
A bidirectional calcium‑redistributing nanomodulator rewires intra‑extracellular calcium homeostasis to remodel tumor mechanical microenvironments. It softens tumor stroma to facilitate deep tissue penetration while stiffening tumor cells, evoking amplified immunogenic cell death and robust CTL infiltration, which achieves potent deep photothermal ...

Peripheral Blood DNA Methylation Changes Precede Lymphoma Diagnosis in Primary Sjögren's Disease

Arthritis &Rheumatology, EarlyView.
Objective Primary Sjögren's disease (SjD) is a systemic autoimmune disease associated with an increased risk of lymphoma. The molecular mechanisms underlying lymphomagenesis remain poorly understood, and sensitive biomarkers for early identification of patients at high risk of developing lymphoma are lacking.

Viscoelastic hydrogel potentiates cancer cell stemness and drug resistance through Piezo1‐dependent mechanotransduction

BMEMat, EarlyView.
The effects of matrix dynamics on cancer progression remain unclear. Herein, we fabricated a tunable dynamic hydrogel via reversible host–guest crosslinking and demonstrated that high matrix dynamics activate Piezo1 and its downstream PI3K/AKT and Wnt/β‐catenin signaling pathways, thereby enhancing cancer spheroid assembly, elevating cancer stemness ...
