A working model for CCN3 C‐terminal domain‐mediated transcriptional modulation of the plasminogen activation system

Journal of Cell Communication and Signaling, Volume 20, Issue 2, June 2026.
Plasminogen is a circulating zymogen that is converted into active plasmin by plasminogen activators such as tissue plasminogen activator (tPA) and urokinase‐type PA (uPA). This conversion is regulated by plasminogen activator inhibitors (PAI‐1, PAI‐2) and by inhibitors of plasmin itself, maintaining a fine balance between activation and inhibition of ...

Hydrogen Sulfide Rescues Microglia From HIV Tat‐Driven Ferroptosis: Implications for HIV‐Associated Neuroinflammation

CNS Neuroscience &Therapeutics, Volume 32, Issue 6, June 2026.
HIV Tat induces ferroptosis and proinflammatory activation in microglia through iron accumulation and oxidative stress. Hydrogen sulfide donor NaHS suppresses HIV Tat‐induced ferroptosis by restoring redox balance, reinforcing the SLC7A11‐GPX4 axis, and attenuating microglial inflammation, highlighting hydrogen sulfide as a potential therapeutic ...

Glycosaminoglycans affect the interaction of human plasma kallikrein with plasminogen, factor XII and inhibitors

Brazilian Journal of Medical and Biological Research, 2003
Human plasma kallikrein, a serine proteinase, plays a key role in intrinsic blood clotting, in the kallikrein-kinin system, and in fibrinolysis. The proteolytic enzymes involved in these processes are usually controlled by specific inhibitors and may be ...

Sensing and Communicating β‐Cell Stress in the Context of T1D Etiology: New Opportunities for Therapeutic Impact

Comprehensive Physiology, Volume 16, Issue 3, June 2026.
Type 1 diabetes (T1D) results from the immune‐mediated destruction of insulin‐producing pancreatic β‐cells. Recent human studies show that early β‐cell stress maladaptations precede overt immune cell infiltration. DOC2B, a vesicle secretion regulatory protein that supports β‐cell functionality and resilience against stress, declines early in T1D ...

High‐Content Immunofluorescence Quantification of Transcription Factors: Application to pSMADs for BMP/TGFβ Signaling Pathways

Current Protocols, Volume 6, Issue 6, June 2026.
Abstract High‐throughput immunofluorescence (IF) detection has become an essential tool in drug discovery for analyzing multiple markers and providing insights into cellular pathways. While IF techniques have been established for decades, high‐content IF protocols vary among laboratories, highlighting the need for standardized and quantitative ...
