Mosquitoes transmit deadly diseases. Chemical repellents deter mosquitoes from approaching or biting a human host and are an effective behavior-based method of personal protection. However, the current standards for selecting repellents often disregard their mode of action. This has likely led many potential repellents to be overlooked. Here, we discuss the sensory systems that underlie host-seeking behavior and how such behaviors are interrupted by repellents. We explore the behavioral assays used to identify repellents and how these have led a handful of contact repellents (DEET, picaridin, IR3535) to dominate the field. Finally, we consider how the development of spatial repellents may further protect against mosquito-borne diseases.

Myeloid-derived IL-33 drives γδ T cell-dependent resistance against cutaneous infection by Strongyloides ratti.

Interleukin 33 (IL-33) is a pleiotropic cytokine released from diverse cell types that regulate both pro- and anti-inflammatory responses during pathogen infection. However, it remains unclear whether IL-33 controls key aspects of cutaneous immunity against skin-penetrating parasites. In this study, mice percutaneously infected with the parasitic helminth Strongyloides ratti were investigated to understand mechanisms of anamnestic immunity at the skin barrier.

Mosquito-borne diseases, including malaria, dengue, chikungunya, and Zika, significantly impact global health. Traditional methods for monitoring human-mosquito contact, such as human landing catch (HLC) and DNA profiling, have limitations, including biases and a lack of detailed temporal and spatial data. HLC may also raise ethical concerns in some settings.

The Argentine ant ( ) is an invasive ant species found across California. Many invasive ant species, including the Argentine ant, can use chemical defense compounds to ward off predators or compete with native ant species, which aids in invasive spread. Previously, Stanford undergraduate researchers found variation in the potency of Argentine ant chemical profiles (collected in varying locations on campus) in repelling during chemotaxis assays.
