A Shift from Cellular to Humoral Responses Contributes to Innate Immune Memory in the Vector Snail Biomphalaria glabrata

PLoS Pathogens, 2016
Discoveries made over the past ten years have provided evidence that invertebrate antiparasitic responses may be primed in a sustainable manner, leading to the failure of a secondary encounter with the same pathogen.

The significance of the amoebocyte-producing organ in Biomphalaria glabrata [PDF]

Memórias do Instituto Oswaldo Cruz, 2012
In molluscs, internal defence against microorganisms is performed by a single cell type, i.e., the haemocyte or amoebocyte. The origin of these cells in Biomphalaria glabrata was initially thought to be localised within the vasculo-connective tissue.

Effect of Biomphalaria straminea plasma in the phagocytosis of Biomphalaria glabrata hemolymph cells [PDF]

Memórias do Instituto Oswaldo Cruz, 1998
Mollusc defensive system that discriminates self from non self molecules, include fixed cells that can trap particles like endothelial cells, reticular and pore-cells, and circulating elements (WPW Van Der Knaap & ES Loker 1990 Parasitol Today 6: 175-182).

Enhancing schistosomiasis drug discovery approaches with optimized proteasome substrates

Protein 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 ...
