Background: Adoptive cell therapy (ACT) with tumor-infiltrating lymphocytes (TIL) is a personalized immunotherapy. The efficacy of TIL-ACT has been demonstrated prospectively in patients with advanced melanoma but is not limited to melanoma patients. Many patients are refractory to TIL-ACT, however, or their cancer becomes resistant.

The increased reports of wild bee declines and annual losses of managed bees pose a significant threat to biodiversity and agricultural productivity. While these losses and declines are likely driven by various factors, the exposure of bees to agrochemicals has raised significant concern due to their ubiquitous use and potential adverse effects. Despite numerous studies suggesting neonicotinoids can negatively affect bees at the behavioral and molecular level, data linking these two factors remains sparse.

Pollinators are essential for crop productivity. Yet, in agricultural areas, they may be threatened by pesticide exposure. Current pesticide risk assessments predominantly focus on honey bees, with a lack of standardized protocols for solitary bees.

Article Synopsis
  • Bees exposed to pesticides like thiamethoxam and pyraclostrobin showed changes in their flight behavior and molecular functions, particularly related to energy metabolism and endocrine regulation.
  • Although no significant effects on survival or return rates were found, pesticide exposure reduced how long foragers spent outside the hive, suggesting that their flight behavior is linked to gene expression changes.
  • Laboratory experiments indicated altered expression of specific genes after pesticide exposure, but more research is required to fully understand how these genes relate to the extended homing flight duration.

In eusocial insects, worker longevity is essential to ensure colony survival in brood-free periods. Trade-offs between longevity and other traits may render long-living workers in brood-free periods more susceptible to pesticides compared to short-lived ones. Further, colony environment (e.
