Mycobacterium avium inhibits protein kinase C and MARCKS phosphorylation in human cystic fibrosis and non-cystic fibrosis cells.

In cystic fibrosis (CF), there is abnormal translocation and function of the cystic fibrosis transmembrane conductance regulator (CFTR) and an upregulation of the epithelial sodium channel (ENaC). This leads to hyperabsorption of sodium and fluid from the airway, dehydrated mucus, and an increased risk of respiratory infections. In this study, we performed a proteomic assessment of differentially regulated proteins from CF and non-CF small airway epithelial cells (SAEC) that are sensitive to Mycobacterium avium.

A case of central sleep apnea associated with chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids.

Unlabelled: A 78-year-old man with history of chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids syndrome, moderate persistent asthma, pansinusitis, and upper airway cough syndrome presented to the sleep medicine clinic for evaluation of sleep-disordered breathing. Brain magnetic resonance imaging showed lesions in the pons and midbrain. Diagnostic polysomnography was remarkable for central sleep apnea.

Lipids and addiction: how sex steroids, prostaglandins, and cannabinoids interact with drugs of abuse.

Lipidomics aims to identify and characterize all endogenous species of lipids and understand their roles in cellular signaling and, ultimately, the functioning of the organism. We are on the cusp of fully understanding the functions of many of the lipid signaling systems that have been identified for decades (e.g.
