P2-Purinoceptors: Advances and therapeutic opportunities.

P2-Purinoceptors: Advances and therapeutic opportunities. Expert Opin Investig Drugs. 1995 Oct;4(10):925-934 Authors: Williams M, Jacobson KA Abstract The recent cloning of a number of distinct receptors belonging to the P2-purinoceptor superfamily has provided conclusive evidence for a pivotal role for ATP and other nucleotides as effector molecules involved in cell-to-cell communication and the modulation of many basic aspects of tissue function. ATP itself is being clinically evaluated as a cytotoxic agent for the treatment of cancer and as an adjunct to inhalation anaesthetic use. The pyrimidine nucleotide, UTP, is in clinical trials for the treatment of cystic fibrosis. The stable ATP bioisostere, ARL 67085, is being developed as a novel antithrombotic agent, blocking with a superior safety profile and increased efficacy as compared to other agents. The diversity of P2 receptors, with eleven having been defined using both pharmacological and molecular cloning criteria, indicates considerable additional potential and subtlety in regard to the effects of ATP on tissue function and pathophysiology.

AbstractPurpose of ReviewThe understanding of the human microbiome, especially of the oral cavity, has expanded exponentially since the advent of 16 rRNA PCR gene sequencing. Since the respiratory tract starts from the oral cavity and ends in the lung, study of the relationship between the oral microbiota and the lungs will allow us to understand the changes in lung disease compared with healthy state.Recent FindingsThe oral and lung microbiota were found to be similar, but the oral microbiota had greater diversity. The oral cavity especially the dorsal tongue was found to be a reservoir for bacteria causing pneumonia and ...

Abstract OBJECTIVES: Family with sequence similarity 13 member A (FAM13A) genetic variants have been associated with several chronic respiratory diseases including chronic obstructive pulmonary disease (COPD), cystic fibrosis (CF), idiopathic pulmonary fibrosis (IPF) and lung cancer. The FAM13A protein includes a RhoGTPase activating protein (RhoGAP) domain known to participate in various cellular mechanisms including cell proliferation. While intensive genomic studies have been performed to reveal its involvement in lung diseases, the biological role of FAM13A protein is still not completely elucidated. RESU...

Abstract Host defense peptides (HDP) are small cationic molecules released by the immune systems of the body, having multidimensional properties including anti-inflammatory, anticancer, antimicrobial and immune-modulatory activity. These molecules gained importance due to their broad-spectrum pharmacological activities, and hence being actively investigated. Presently, respiratory infections represent a major global health problem, and HDP has an enormous potential to be used as an alternative therapeutics against respiratory infections and related inflammatory ailments. Because of their short half-life, protease ...

Aim: To determine the characteristics of chronic lung diseases in patients with mycobacterioses caused by slowly growing nontuberculous mycobacteria (NTM).We studied 51 patients with pulmonary mycobacterioses caused by slowly growing NTM; the average age was 54.1±0.3 yrs; disease duration was 19.5±0.5 months. In all patients the diagnosis was microbiologically verified. Out of them 25 (49%) were infected with M. avium, 21.5% – M. intracellulare, 9.8% – M. kansasii, 5.8% – M. xenopi, 3.9% – M. gordonae, 3.9% – M. lentiflavum. Four patients were co-infected with M. avium + M. intra...

Pancreatic exocrine insufficiency occurs when there is insufficient production or delivery of pancreatic enzymes required for the digestion and absorption of food. It is associated with relatively poor outcomes, including reduced quality of life and survival.1 Common causes are cancer of the head/body of the pancreas, chronic pancreatitis, pancreatic resection and cystic fibrosis. It can occur following duodenectomy, gastrectomy or untreated coeliac disease via a reduction in cholecystokinin and thereby post-prandial pancreatic stimulation.
