ABSTRACTThe constant composition of body fluids in insects is maintained by the cooperative interaction of gastrointestinal and urinary tissues. Water follows ionic movements, which are driven by the basolateral Na+/K+-ATPase and/or the apical ‘K+(or Na+) pump’.

Brain ion homeostasis in cerebral ischemia
Neurochemical Pathology, 1988Brain function is severely disturbed in ischemia. Within seconds, consciousness and spontaneous activity is lost, whereas interstitial concentrations of major ions are kept near normal levels. After a few minutes, there is a dramatic increase of potassium and a lowering of sodium, chloride, and calcium concentrations. Similar ionic changes are observed

Metal ion homeostasis in Bacillus subtilis
Current Opinion in Microbiology, 2005Bacillus subtilis, a Gram-positive soil bacterium, provides a model system for the study of metal ion homeostasis. Metalloregulatory proteins serve as the arbiters of metal ion sufficiency and regulate the expression of metal homeostasis pathways. In B.

Calcium ion homeostasis in smooth muscle
Pharmacology & Therapeutics, 1992Ca2+ plays an important role in the regulation of smooth-muscle contraction. In this review, we will focus on the various Ca(2+)-transport processes that contribute to the cytosolic Ca2+ concentration. Mainly the functional aspects will be covered.

Metal ion homeostasis and intracellular parasitism
Molecular Microbiology, 1998Bacteria possess multiple mechanisms for the transport of metal ions. While many of these systems may have evolved in the first instance to resist the detrimental effects of toxic environmental heavy metals, they have since become adapted to a variety of important homeostatic functions.

Identification of proteins associated with ion homeostasis and salt tolerance in barley
Proteomics, 2014 Identification and characterization of proteins involved in salt tolerance are imperative for revealing its genetic mechanisms. In this study, ionic and proteomic responses of a Tibetan wild barley XZ16 and a well-known salt-tolerant barley cv. CM72 were

Ion homeostasis in diabetic kidney disease
Trends in Endocrinology & MetabolismThe complications of type 2 diabetes are a major global public health problem with high incidence and mortality, affecting almost all individuals with diabetes worldwide. Diabetic kidney disease (DKD) is one such primary complication and has become a leading cause of end-stage renal disease in patients with diabetes. Progression from diabetes to DKD is

Ion homeostasis and ion channels in NLRP3 inflammasome activation and regulation
Current Opinion in Immunology, 2018The NLRP3 inflammasome is a multiprotein platform for the activation of caspase-1, which in turn drives inflammation through the activation of proinflammatory cytokines, such as IL-1β. In contrast to the majority of pattern recognition receptors, NLRP3 inflammasome can be triggered by a plethora of pathogen-derived or endogenous activators, which ...

Golgi pH and Ion Homeostasis in Health and Disease
2020Maintenance of the main Golgi functions, glycosylation and sorting, is dependent on the unique Golgi pH microenvironment that is thought to be set by the balance between the rates of V-ATPase-mediated proton pumping and its leakage back to the cytoplasm via an unknown pathway.

The neurobiology of glia in the context of water and ion homeostasis
Neuroscience, 2004Astrocytes are highly complex cells that respond to a variety of external stimulations. One of the chief functions of astrocytes is to optimize the interstitial space for synaptic transmission by tight control of water and ionic homeostasis. Several lines of work have, over the past decade, expanded the role of astrocytes and it is now clear that ...
