Competent Non‐Native Alternative Host Reduces Infection Success in a Generalist Parasite

Ecology and Evolution, Volume 16, Issue 6, June 2026.
In this study, we experimentally assessed how the addition of a non‐native alternative host affects the infection success of the larval generalist trematode, Diplostomum pseudospathaceum, in fish intermediate hosts. Our results demonstrate that the presence of alternative hosts, especially the non‐native ones, can reduce parasite transmission through ...

Changes in the Prevalence of Natural Paramphistomum Cercariae Infection in Indoplanorbis and Lymnaea Intermediate Hosts Influenced by Meteorological Factors

Journal of Tropical Medicine, 2022
Paramphistomosis is a neglected ruminant parasitic disease caused by trematodes known as Paramphistomum, which has a diheteroxenic life cycle involving freshwater snail genera, i.e., Planorbis and Lymnaea as the intermediate host and mammals as the ...

Inter‐Annual Variation in Alpha and Beta Diversity of Benthic Macroinvertebrate Communities in Agricultural Ditches

River Research and Applications, Volume 42, Issue 5, Page 997-1010, June 2026.
ABSTRACT Ditches are essential elements of the agricultural landscape because of their role as habitat or refuge for aquatic species, especially in homogenized and intensively cultivated areas. However, data on the biodiversity associated with agricultural ditches, and its variation over time, are underrepresented in ecological research.

Monoamines, Insulin and the Roles They Play in Associative Learning in Pond Snails

Frontiers in Behavioral Neuroscience, 2019
Molluscan gastropods have long been used for studying the cellular and molecular mechanisms underlying learning and memory. One such gastropod, the pond snail Lymnaea stagnalis, exhibits long-term memory (LTM) following both classical and operant ...

Conkazal‐M1 from the MKAVA family of conotoxins: A dual‐function protease inhibitor and neuroactive peptide

Protein Science, Volume 35, Issue 5, May 2026.
Abstract Marine cone snails produce a diverse array of bioactive peptides, known as conotoxins, in their venom. Given their high target potency and specificity, conotoxins are attractive compounds for the development of precision research tools and pharmacological agents.

Mapping molluscan endocrinology: a systematic and critical appraisal

Biological Reviews, Volume 101, Issue 2, Page 970-1002, April 2026.
ABSTRACT Historically, a vertebrate‐centric paradigm has framed our interpretation of molluscan endocrinology, with considerable research focusing on vertebrate‐type steroid hormones (e.g. oestrogens, testosterone). However, contradictory evidence on the occurrence of vertebrate‐type steroid hormones in molluscan tissues, and a lack of the specific ...

Selective Depletion of Autoreactive Plasma Cells as a Novel Strategy to Treat Acetylcholine Receptor Antibody‐Positive Myasthenia Gravis

European Journal of Immunology, Volume 56, Issue 4, April 2026.
Current plasma cell–targeting therapies lack antigen specificity. Using an antibody‐mediated cytotoxicity engager (ACE) targeting the α‐subunit of the extracellular domain of the human acetylcholine receptor (hAChR αECD), we selectively depleted pathogenic antibody‐secreting cells in a myasthenia gravis model, reducing autoantibody titers and disease ...
