Despite significant research efforts, a therapy to slow or halt the progression of Parkinson's disease ("neuroprotection") remains elusive. The discovery of such a therapy will likely require important observations from a number of perspectives: basic science investigation, clinical research, and careful observation in medical practice. Any possible insights will require confirmation in rigorous clinical trial testing. Combining the useful insights from all perspectives may be the most promising approach to discovering a neuroprotective therapy.

Drug-based therapies for vascular disease in Marfan syndrome: from mouse models to human patients.
Marfan syndrome is a congenital disorder of the connective tissue with a long history of clinical and basic science breakthroughs that have forged our understanding of vascular-disease pathogenesis. The biomedical importance of Marfan syndrome was recently underscored by the discovery that the underlying genetic lesion impairs both tissue integrity and transforming growth factor-beta regulation of cell behavior. This discovery has led to the successful implementation of the first pharmacological intervention in a connective-tissue disorder otherwise incurable by either gene-based or stem cell-based therapeutic strategies. More generally, information gathered from the study of Marfan syndrome pathogenesis has the potential to improve the clinical management of common acquired disorders of connective-tissue degeneration.

Over the past 2 decades, our increased understanding of tumor biology has resulted in the delivery of a new generation of molecularly targeted cancer drugs with greater efficacy and less toxicity. This understanding has also provided pharmaceutical and academic institutions with a greater appreciation for the complexities and challenges associated with discovering and developing molecularly targeted drugs. ⋯ Cooperative efforts by industry and academia have also provided important insights to optimize the use of such agents in the clinic. This review aims to emphasize the need for academic/industrial collaborations for success and efficiency through the drug discovery and development continuum, and will highlight several examples of collaborations between academic and industrial scientists that facilitated the development of molecularly targeted antitumor agents into the clinic.

G-protein-coupled receptors are important molecular targets in drug discovery. These receptors play a pivotal role in physiological signaling pathways and are targeted by nearly 50% of currently available drugs. Mounting evidence suggests that G-protein-coupled receptors form dimers, and various studies have shown that dimerization is necessary for receptor maturation, signaling, and trafficking. ⋯ Such antibodies could be used as tools for characterization of heteromer-specific function; as reagents for their purification, tissue localization, and regulation in vivo; and as probes for mapping their functional domains. In addition, such antibodies could serve as alternative ligands for G-protein-coupled receptor heteromers. Thus, heteromer-specific antibodies represent novel tools for the exploration and manipulation of G-protein-coupled receptor-dimer pharmacology.
