Current Pharmaceutical Design - Volume 12, Issue 5, 2006

Recently several issues of Current Pharmaceutical Design have been dedicated to cytokines and their clinical applications. The topics on conventional and novel aspects in the field have been extensively covered by the reviews in them. As such, my purpose is to bring up-to-date information on somewhat "atypical" cytokine-related therapies. In this issue of Current Pharmaceutical Design, I invited six experts and t Read More

This review summarises some of the knowledge we have about Crk and Grb2 family adaptor protein signalling in health and disease and outlines the current status and the challenges still remaining in the development of efficient and selective inhibitors of their protein - protein interactions. It also highlights briefly some recent successes and problems of inhibitors for proteins that functionally interact with Crk and Grb2 family a Read More

The progress of clinical gene therapy trials during the last two decades has been remarkable, and its application has also expanded into various fields of human diseases. Among them, hereditary diseases such as the primary immunodeficiency diseases (PID) were considered suitable candidates for gene therapy because the therapeutic strategy was very simple, therefore, effective gene therapy may be obtained with Read More

Despite considerable progress in the field of cardiovascular medicine and surgery, ischemic heart disease is still the leading cause of death in advanced countries. In this context, it is no wonder why therapeutic angiogenesis, a way to ameliorate ischemic tissue from suffering dysfunction by increasing new blood vessels, gains so much attention from both clinicians and patients. In this review, we will briefly go through a de Read More

Cilostazol was developed as a selective inhibitor of cyclic nucleotide phosphodiesterase 3 (PDE3). The antiplatelet and vasodilator properties of cilostazol have been extensively characterized and considered to contribute to the variety of clinical effects such as intermittent claudication and recurrent stroke. In this review, the novel action mechanism (s) of cilostazol are overviewed with the focus on the action of cilostazol in i Read More

Blood platelets are very unique in that they store sphingosine 1-phosphate (Sph-1-P) abundantly (possibly due to the existence of highly active sphingosine kinase and a lack of Sph-1-P lyase) and release this bioactive lipid extracellularly upon stimulation. Vascular endothelial cells (ECs) and smooth muscle cells (SMCs) respond dramatically to this platelet-derived bioactive lipid mainly through a family of G protein-coupled Sp Read More

Pulmonary surfactant, a complex of lipids and proteins, functions to keep alveoli from collapsing at expiration. Surfactant proteins A (SP-A) and D (SP-D) belong to the collectin family and play pivotal roles in the innate immunity of the lung. Pulmonary collectins directly bind with broad specificities to a variety of microorganism and possess antimicrobial effects. These proteins also exhibit both inflammatory and anti-infla Read More

Tobacco use is the leading risk factor for lung cancer, yet in addition to smoking habit, diet may also play a role in the disease's appearance. While there are reports to indicate that antioxidant vitamins and carotenoids may decrease the risk of lung cancer, results to date have been somewhat ambiguous. This review aimed to describe the results yielded by different studies, which have addressed antioxidant vitamin intake and l Read More

The calpains represent a well-conserved family of calcium-dependent cysteine proteases. They consist of several ubiquitous and tissue specific isoforms and exhibit broad substrate specificity influencing many aspects of cell physiology including migration, proliferation and apoptosis. Calpain activity in vivo is tightly regulated by its natural endogenous inhibitor calpastatin. Calpastatin specifically inhibits calpain and not other cy Read More

Recent glycobiology studies have suggested fundamental biological functions for chondroitin sulfate (CS) and dermatan sulfate (DS), which are widely distributed as glycosaminoglycans (GAGs) sidechains of proteoglycans (PGs) in the extracellular matrix and at cellular level. Several biological functions are closely associated with the structure and in particular with the sulfation patterns of these polysaccharides. CS is Read More
