Ionizing radiation enhances immunogenicity of cells expressing a tumor-specific T-cell epitope.

BACKGROUND: p53 point mutations represent potential tumor-specific cytolytic T lymphocyte (CTL) epitopes. Whether ionizing radiation (IR) alters the immunological properties of cells expressing mutant p53 in respect of the CTL epitope generated by a defined point mutation has not been evaluated. METHODS: Mutant p53-expressing syngeneic, nontumor forming BALB/c 3T3 fibroblasts, tumor forming ras-transfected BALB/c 3T3 sarcomas, and DBA/2-derived P815 mastocytoma cells, which differ at the level of minor histocompatibility antigens, were used as cellular vaccines. Cells were either injected with or without prior IR into naive BALB/c mice. Cellular cytotoxicity was assessed after secondary restimulation of effector spleen cells in vitro. RESULTS: Injection of P815 mastocytoma cells expressing the mutant p53 induced mutation-specific CTL in BALB/c mice irrespective of prior irradiation. However, syngeneic fibroblasts or fibrosarcomas endogenously expressing mutant p53 were able to induce significant mutation-specific CTL only when irradiated prior to injection into BALB/c mice. IR of fibroblasts did not detectably alter the expression of cell surface molecules involved in immune response induction, nor did it alter the short-term in vitro viability of the fibroblasts. Interestingly, radioactively-labeled fibroblasts injected into mice after irradiation showed altered organ distribution, suggesting that the in vivo fate of these cells may play a crucial role in their immunogenicity. CONCLUSIONS: These findings indicate that IR can alter the immunogenicity of syngeneic normal as well as tumor forming fibroblasts in vivo, and support the view that ionizing radiation enhances immunogenicity of cellular tumor vaccines.

Molecular and social regulation of worker division of labour in fire ants.

Reproductive and worker division of labour (DOL) is a hallmark of social insect societies. Despite a long-standing interest in worker DOL, the molecular mechanisms regulating this process have only been investigated in detail in honey bees, and little is known about the regulatory mechanisms operating in other social insects. In the fire ant Solenopsis invicta, one of the most studied ant species, workers are permanently sterile and the tasks performed are modulated by the worker's internal state (age and size) and the outside environment (social environment), which potentially includes the effect of the queen presence through chemical communication via pheromones. However, the molecular mechanisms underpinning these processes are unknown. Using a whole-genome microarray platform, we characterized the molecular basis for worker DOL and we explored how a drastic change in the social environment (i.e. the sudden loss of the queen) affects global gene expression patterns of worker ants. We identified numerous genes differentially expressed between foraging and nonforaging workers in queenright colonies. With a few exceptions, these genes appear to be distinct from those involved in DOL in bees and wasps. Interestingly, after the queen was removed, foraging workers were no longer distinct from nonforaging workers at the transcriptomic level. Furthermore, few expression differences were detected between queenright and queenless workers when we did not consider the task performed. Thus, the social condition of the colony (queenless vs. queenright) appears to impact the molecular pathways underlying worker task performance, providing strong evidence for social regulation of DOL in S. invicta.

Division of Tobacco Use prevention and Control 2014-2018 Strategic Plan,

The Division of Tobacco Use Prevention and Control works to reduce tobacco use and the toll of tobacco-caused disease and death by preventing youth from starting, helping Iowans to quit, and preventing exposure to secondhand smoke. Tobacco is the leading preventable cause of death for Iowans, taking the lives of more than 4,400 adults each year. Estimated annual health care costs in Iowa directly related to tobacco use now total $1 billion.
