Unveiling the Leishmanicidal Mechanism of 4‐Nerolidylcatechol Isolated From Piper peltatum Against Leishmania infantum

Chemistry &Biodiversity, Volume 23, Issue 1, January 2026.
ABSTRACT The present study assessed the leishmanicidal activity of 4‐nerolidylcatechol (4‐NC) (1) isolated from Piper peltatum leaves against promastigotes and amastigotes of Leishmania amazonensis, L. braziliensis, and L. infantum. The plant was fractionated, leading to the isolation and chemical identification of 4‐NC (1). Biochemical techniques were

The Sensory Ecology of Tsetse Flies: Neuroscience Perspectives on a Disease Vector

European Journal of Neuroscience, Volume 63, Issue 2, January 2026.
Tsetse flies (Glossina sp.) are important disease vectors that feed on vertebrate blood. Host‐seeking depends on a combination of sensory systems, from long‐range senses like olfaction and vision, to shorter‐range senses such as audition, mechanosensation, thermosensation and taste.

Sex in Immune Cells and Parasitic Diseases — A Complex Relationship

Immunological Reviews, Volume 337, Issue 1, January 2026.
ABSTRACT Epidemiological studies consistently show that many parasitic diseases affect males more frequently than females. These disparities are multifactorial, arising partly from gender‐specific behaviors that influence exposure risk and health‐seeking practices, especially in low‐ and middle‐income countries. Increasing evidence also highlights that
