ReviewThe angiopoietin-Tie2 system as a therapeutic target in sepsis and acute lung injury.
Sepsis and acute lung injury (ALI)/acute respiratory distress syndrome (ARDS) are life-threatening syndromes characterised by inflammation and increased vascular permeability. Amongst other factors, the angiopoietin-tyrosine kinase with immunoglobulin-like and EGF-like domains 2 (Tie2) system is involved. ⋯ The angiopoietin-Tie2 system controls the responsiveness of the endothelium to inflammatory, hyperpermeability, apoptosis and vasoreactive stimuli. Angiopoietin-2 provokes inflammation and vascular hyperpermeability, while angiopoietin-1 has a protective effect. Targeted angiopoietin-2 inhibition with RNA aptamers or blocking antibodies is a potential anti-inflammatory and anti-vascular hyperpermeability strategy in the treatment of sepsis and ALI/ARDS.

ReviewTRP channels as emerging targets for pain therapeutics.
The transient receptor potential (TRP) superfamily of ion channels are a large and diverse group that have received increased attention in recent years. The sub-family of thermo-TRPs which are regulated by temperature, among other physical and chemical stimuli, are of particular interest for the development of potential pain therapeutics. ⋯ Vanilloid-type TRP 1 (TRPV1) is the most well studied and advanced member of the family, with selective agonists and antagonists already in clinical use or development, respectively. Among other thermo-TRPs (including TRPV2 - 4, Ankyrin type TRP 1 (TRPA1) and melastatin type TRP 8 (TRPM8)), TRPA1 and TRPM8 are emerging as promising novel pain targets.
