The myo-inositol-1-phosphate synthase (MIPS) catalyses the biosynthesis of myo-inositol, an important sugar that regulates various physiological and biochemical processes in plants. Here, we provide evidence that host (SlMIPS1) and pathogen (Rs_MIPS) myo-inositol-1-phosphate synthase (MIPS) genes are required for successful infection of Rhizoctonia solani, a devastating necrotrophic fungal pathogen, in tomato. Silencing of either SlMIPS1 or Rs_MIPS prevented disease, whereas an exogenous spray of myo-inositol enhanced disease severity.

Ultrasound (US)-responsive carriers have emerged as promising theranostic candidates because of their ability to enhance US-contrast, promote image-guided drug delivery, cause on-demand pulsatile release of drugs in response to ultrasound stimuli, as well as to enhance the permeability of physiological barriers such as the stratum corneum, the vascular endothelium, and the blood-brain barrier (BBB). US-responsive carriers include microbubbles MBs, liposomes, droplets, hydrogels, and nanobubble-nanoparticle complexes and have been explored for cavitation-mediated US-responsive drug delivery. Recently, a transient increase in the permeability of the BBB by microbubble (MB)-assisted low-frequency US has shown promise in enhancing the delivery of therapeutic agents in the case of neurological disorders.

Neurokinin (NK) peptides such as substance P (SP) may modulate epithelial ion transport in the small intestine. The present study was undertaken to examine the pharmacological mechanisms by which SP and its endogenous homologs NKA and NKB affect active electrolyte transport in the mucosa of porcine jejunum. Neurokinins and NK agonist analogs increased short circuit current, a measure of active ion transport, across sheets of jejunal mucosa-submucosa with the order of potency: SP greater than [beta-Ala8]NKA4-10 greater than or equal to [Sar9,Met(O2)11]SP greater than NKA = Arg-NKB greater than NKB after their addition to the serosal aspect of tissues (SP EC50 = 11 nM).

Acetylcholine is present in a majority of submucosal neurons which project to the intestinal epithelium. In this study, we examined the role of acetylcholine and the actions of cholinomimetic drugs, such as carbachol (CCH), on ion transport across muscle-stripped sheets of mucosa-submucosa from the proximal jejunum of weaned piglets. Serosal administration of CCH (10 nM-100 microM) produced rapid increases in short-circuit current (Isc) which were attributed to net Cl secretion.

The neurotransmitter acetylcholine is thought to modulate epithelial ion transport in the mammalian small intestine. In this study, the non-selective acetylcholine agonist, carbachol, produced rapid changes in short-circuit current (Isc), an electrical measure of active anion secretion, across isolated sheets of the distal jejunal mucosa-submucosa from swine. The potency of carbachol in elevating Isc was decreased 26-fold in the presence of 10 nM atropine, but remained unchanged by 1-100 microM hexamethonium or 0.
