We are currently facing important challenges to prevent and cure neurological disorders that are becoming a major public health issue in our aging society. Because of the lack of mechanism-based treatments to correct brain malformations or to prevent the progression of cell death in neurodegenerative disorders, most of these pathologies follow a fatal course. Thus, one major objective is to understand the molecular events that underlie these diseases in order to prevent their onset and/or halt their progression. Converging experimental and clinical evidences obtained by our lab and others prompt us to speculate that Elongator may be commonly targeted in different neurological disorders and as such, should represent a strong candidate for research and development efforts to design drug-based therapies.

Experimental models indicate that tumor cells in suspension, unlike solid tumor fragments, might be unable to produce life-threatening cancer outgrowth when transferred to animal models, irrespective of the number of cells transferred, although they induce specific immune responses. Human tumor cells cultured in three dimensions display increased pro-angiogenic capacities and resistance to interferons, chemotherapeutic agents or irradiation, as compared with cells cultured in two-dimensional (2D) monolayers. Tumor cells cultured in three dimensions were also shown to be characterized by defective immune recognition by cytotoxic T lymphocytes (CTLs) specific for tumor-associated antigens (TAAs) and by a capacity to inhibit CTL proliferation and dendritic cell (DC) functions. Downregulation of human leukocyte antigen (HLA) or TAA expression and high production of lactic acid might play a role in the elicitation of these effects. Here, we propose that growth in 3D architectures might provide new insights into tumor immunology and could represent an integral missing component in pathophysiological tumor immune escape mechanisms.

Age-related macular degeneration (AMD) is the leading cause of blindness in elderly patients. The more aggressive exudative form is characterized by abnormal blood-vessel development that occurs beneath the retina as a result of choroidal neovascularization (CNV). Vascular endothelial growth factor [VEGF) has emerged as the key mediator of CNV formation; this has led to intensive research on VEGF and the recent approval of anti-VEGF compounds by the US Food and Drug Administration. Despite this successful introduction of anti-angiogenic therapies into the clinical setting, there is still a lack of treatments that definitively reverse damaged vision. Here, we consider the importance of putative molecular targets other than VEGF that might have been underestimated. Emerging cellular mechanisms offer additional opportunities for innovative therapeutic approaches. [less ▲]
