The immunopathogenesis of a cytokine storm: The key mechanisms underlying severe COVID-19.
Cytokine Growth Factor Rev
January 2025
Faculty of Pharmacy, University of Ljubljana, Slovenia. Electronic address:
A cytokine storm is marked by excessive pro-inflammatory cytokine release, and has emerged as a key factor in severe COVID-19 cases - making it a critical therapeutic target. However, its pathophysiology was poorly understood, which hindered effective treatment. SARS-CoV-2 initially disrupts angiotensin signalling, promoting inflammation through ACE-2 downregulation.

Background: In addition to its important roles in blood coagulation and bone formation, vitamin K (VK) contributes to brain function. Low dietary VK intake, which is common among older adults, is associated with age-related cognitive impairment.
Objective: To elucidate the biological mechanisms underlying VK's effects on cognition, we investigated the effects of low VK (LVK) intake on cognition in C57BL/6 mice.
The role of vitamin K2 in cognitive impairment: linking vascular health to brain health.

Cognitive impairment, marked by a decline in essential mental aspects such as attention, memory, and problem-solving, is significantly correlated with advancing age. This condition presents a major challenge for the elderly, adversely affecting quality of life, diminishing independence, and imposing substantial burdens on healthcare systems. Recent research indicates that vitamin K2 may be vital for preserving brain health and cognitive function.

Blood clots (BCs) play a crucial biomechanical role in promoting osteogenesis and regulating mesenchymal stem cell (MSC) function and fate. This study shows that BC formation enhances MSC osteogenesis by activating Itgb1/Fak-mediated focal adhesion and subsequent Runx2-mediated bone regeneration. Notably, BC viscoelasticity regulates this effect by modulating Runx2 nuclear translocation.

Immune thrombocytopenic purpura (ITP) is an acquired immune-mediated bleeding disorder characterized by isolated low platelet (PLT) counts. Immune thrombocytopenic purpura pathogenesis involves multiple immune mechanisms causing PLT destruction and inadequate production. Owing to impaired immune homeostasis, ITP patients can develop other than anti-PLT autoantibodies even in the absence of clinical signs of autoimmune disease, such as anti-thyroglobulin (TG) and anti-thyroperoxidase (TPO) antibodies.
