[Lysine Succinylation:A New Perspective in the Treatment of Cardiovascular Diseases].

With the continuous development of identification technologies such as mass spectrometry,omics,and antibody technology,post-translational modification (PTM) has demonstrated increasing potential in medical research.PTM as a novel chemical modification method provides new perspectives for the research on diseases.Succinylation as a novel modification has aroused the interest of more and more researchers.The available studies about succinylation mainly focus on a desuccinylase named sirtuin 5.This enzyme plays a key role in modification and has been preliminarily explored in cardiovascular studies.This paper summarizes the influencing factors and regulatory roles of succinylation and the links between succinylation and other PTMs and reviews the research progress of PTMs in the cardiovascular field,aiming to deepen the understanding about the role of this modification and give new insights to the research in this field.

Cytokine storm and targeted therapy in hemophagocytic lymphohistiocytosis.

Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening systemic hyperinflammatory syndrome. The central pathogenesis is an explosive cytokine storm characterized by a significant increase in proinflammatory cytokines, including IL-1ß, IL-6, IL-18, IFN-γ, and TNF-α. Meanwhile, negative regulatory factors, such as IL-10 and TGF-ß, are also related to the production of HLH. Exploring the specific mechanism of cytokine storms could provide ideas regarding targeted therapy, which could be helpful for early treatment to reduce the mortality of HLH. Although some research has focused on the advantages of targeted therapies, there is still a lack of a comprehensive discourse. This article attempts to summarize the mechanisms of action of various cytokines and provide a therapeutic overview of the current targeted therapies for HLH.
