Traditional Chinese herbal medicine at the forefront battle against COVID-19: Clinical experience and scientific basis.

2020

Abstract Background Throughout the 5000-year history of China, more than 300 epidemics were recorded. Traditional Chinese herbal medicine (TCM) has been used effectively to combat each of these epidemics’ infections, and saved many lives. To date, there are hundreds of herbal TCM formulae developed for the purpose of prevention and treatment during epidemic infections. When COVID-19 ravaged the Wuhan district in China in early January 2020, without a deep understanding about the nature of COVID-19, patients admitted to the TCM Hospital in Wuhan were immediately treated with TCM and reported later with >90% efficacy. Approach We conducted conduct a systematic survey of various TCM herbal pre…

Can the TLR-4-mediated signaling pathway be "a key inflammatory promoter for sporadic TAA"?

2014

Thoracic aorta shows with advancing age various changes and a progressive deterioration in structure and function. As a result, vascular remodeling (VR) and medial degeneration (MD) occur as pathological entities responsible principally for the sporadic TAA onset. Little is known about their genetic, molecular, and cellular mechanisms. Recent evidence is proposing the strong role of a chronic immune/inflammatory process in their evocation and progression. Thus, we evaluated the potential role of Toll like receptor- (TLR-) 4-mediated signaling pathway and its polymorphisms in sporadic TAA. Genetic, immunohistochemical, and biochemical analyses were assessed. Interestingly, the rs4986790 TLR4…

Toll-like receptor-4 signaling pathway in aorta aging and diseases: “its double nature”

2017

Recent advances in the field of innate immunity have revealed a complex role of innate immune signaling pathways in both tissue homeostasis and disease. Among them, the Toll-like receptor 4 (TLR-4) pathways has been linked to various pathophysiological conditions, such as cardiovascular diseases (CVDs). This has been interrogated by developing multiple laboratory tools that have shown in animal models and clinical conditions, the involvement of the TLR-4 signaling pathway in the pathophysiology of different CVDs, such as atherosclerosis, ischemic heart disease, heart failure, ischemia-reperfusion injury and aorta aneurysm. Among these, aorta aneurysm, a very complex pathological condition w…

Cytokine Polymorphism in Takotsubo Cardiomyopathy

2014

IMIN11. Cytokine Polymorphism in Takotsubo Cardiomyopathy P. Di Gangi1, L. Scola1, S. Giambanco1, M. Bova1, G. Santini1, L. Vaccarino1, C. R. Balistreri1, D. Lio1, P. Assennato1, S. Novo1, G. Novo1 1University of Palermo, Palermo, Italy Background: Takotsubo (TT) cardiomyopathy is characterised by an acute left ventricular dysfunction triggered by emotional or physical stresses. Clinically, the syndrome is characterised by acute symptoms mimicking acute infarction without relevant electrocardiographic and biochemical markers of myocardial damage changes. Stressful events inducing an excess catecholamine release and myocardial β-adrenergic receptors (β-AR) seem to play a major role in TT. Ac…

HSP60 activity on human bronchial epithelial cells

2017

HSP60 has been implicated in chronic inflammatory disease pathogenesis, including chronic obstructive pulmonary disease (COPD), but the mechanisms by which this chaperonin would act are poorly understood. A number of studies suggest a role for extracellular HSP60, since it can be secreted from cells and bind Toll-like receptors; however, the effects of this stimulation have never been extensively studied. We investigated the effects (pro- or anti-inflammatory) of HSP60 in human bronchial epithelial cells (16-HBE) alone and in comparison with oxidative, inflammatory, or bacterial challenges. 16-HBE cells were cultured for 1–4 h in the absence or presence of HSP60, H2O2, lipopolysaccharide (…
