Unexpected trophic diversity in the endemic fish Orestias chungarensis in a high‐altitude freshwater ecosystem, Lake Chungará (4520 m), northern Chile

open access: yesJournal of Fish Biology, Volume 107, Issue 3, Page 837-850, September 2025.
Abstract Orestias chungarensis Vila & Pinto, 1986 is a small‐bodied (max fork length = 120 mm) cyprinodontiform fish with a very restricted global distribution. The species is limited to a single, small (283 km2), high‐altitude (4520 m) catchment located in the Altiplano of northern Chile. Until the late 20th century, O.

Pharmacological Inhibition of c‐Jun N‐Terminal Kinase Activity Exacerbates Liver Damage in Schistosoma mansoni Infected Mice

open access: yesLiver International, Volume 45, Issue 9, September 2025.
ABSTRACT Background and Aims Schistosomiasis is a neglected tropical disease affecting more than 250 million people worldwide. Eggs of the parasitic helminth S. mansoni cause major morbidity in the liver, spleen and intestine. Of note, egg‐released soluble antigens (SEA) induce the transcription factor c‐Jun in hepatocytes, promoting hepatocellular ...

Enhancing schistosomiasis drug discovery approaches with optimized proteasome substrates

open access: yesProtein Science, Volume 34, Issue 6, June 2025.
Abstract Schistosomiasis, a neglected tropical disease infecting over 200 million people globally, has limited therapeutic options. The 20S proteasome is a validated drug target for many parasitic infections, including those caused by Plasmodium and Leishmania, and we have previously demonstrated antischistosomal activity with inhibitors targeting ...
