Method of detecting and counting bacteria [PDF]

, 1976
An improved method is provided for determining bacterial levels, especially in samples of aqueous physiological fluids. The method depends on the quantitative determination of bacterial adenosine triphosphate (ATP) in the presence of nonbacterial ATP ...

Inhibition of RACK1‐Mediated NLRP3 Oligomerization (Active Conformation) Ameliorates Acute Respiratory Distress Syndrome

Advanced Science, EarlyView.
Schematic diagram showing the potential mechanism of bigelovin on the activation of NLRP3 inflammasome Bigelovin may inhibit activated protein C kinase 1 (RACK1) by directly binding with cys168 of RACK1. Bigelovin thus prevents oligomerization of NLRP3 (NLRP3 active conformation) and subsequent assembly of NLRP3 inflammasome, blocking the activation of

Erythrocytes Induce Endothelial Injury in Type 2 Diabetes Through Alteration of Vascular Purinergic Signaling

Frontiers in Pharmacology, 2020
It is well established that altered purinergic signaling contributes to vascular dysfunction in type 2 diabetes (T2D). Red blood cells (RBCs) serve as an important pool for circulating ATP and the release of ATP from RBCs in response to physiological ...

Intracellular compartmentalization of adenosine triphosphate.

Journal of Biological Chemistry, 1986
The intracellular distribution and diffusivity of adenosine triphosphate (ATP) was studied by cryomicrodissection of individual Rana pipiens oocytes. We measured ATP concentrations in the nucleus, in animal and vegetal hemisphere cytoplasm, and in an intracellular reference phase (iRP, a microinjected gelatin "organelle") which samples diffusive ATP ...

Single‐Cell Analysis Clarifies Pathological Heterogeneity in Tenosynovial Giant Cell Tumor and Identifies Biomarkers for Predicting Disease Recurrence

Advanced Science, EarlyView.
MP3 tumor cells, a specific subpopulation of tumor cells in D‐TGCT, regulated the differentiation of CD34+ Fbs into MMP3+ Fbs and APOE+ Fbs through COL6A3 − (ITGAV + ITGB8) interaction. APOE+ Fbs activated IL‐1B+CCL20+ Mφs through the CXCL12/CXCR4 axis. IL‐1B+CCL20+ Mφs and MMP3+ Fbs participated in the local invasion of D‐TGCT.
