Responses of a large herbivore to predation risk are modulated by intrinsic and extrinsic factors

open access: yesEcosphere, Volume 16, Issue 5, May 2025.
Abstract Prey species can perceive and respond to spatiotemporal variation in predation risk to increase survival. In addition to adjusting spatial and temporal activity patterns to avoid predation, prey employ other antipredator behaviors, such as vigilance and fleeing, and these behaviors can be further modulated by intrinsic, environmental, and ...

Taming interleukin‐12: Engineering of bispecific antibody‐based IL‐12 mimetics with biased agonism capacities

open access: yesProtein Science, Volume 34, Issue 3, March 2025.
Abstract In this work, we have generated bispecific interleukin (IL)‐12 surrogate agonists based on camelid‐derived single‐domain antibodies (sdAbs) targeting the IL‐12 receptor (IL‐12R) subunits IL‐12Rβ1 and IL‐12Rβ2. Following immunization and antibody display‐based paratope isolation, respective sdAbs were combinatorially reformatted into a ...
