Quorum-sensing-mediated interactions between Trypanosoma congolense and Trypanosoma brucei promote the differentiation of T. brucei into transmissible ‘stumpy forms’, suggesting that cross-species interactions during co-infections modulate disease dynamics.
For reproduction, the human parasite Schistosoma japonicum relies on a complex and incompletely understood interplay between female and male schistosomes. Here the authors sequence the transcriptome of female and male schistosomes across eight time points during sexual development.
Oocyst rupture and release of malaria sporozoites is needed for transmission of parasites from vector to humans. Here the authors identify two proteins, which they name ORP1 and ORP2, that form heterodimers and are required for oocyst rupture.
Giardia lamblia is a human protozoan parasite with two diploid nuclei, which makes complete knock-out of a gene of interest challenging. Here the authors use a Cre/loxP-based approach to knock-out cyst-wall protein 1 (cwp1) and show that CWP1 is essential for cyst-wall biosynthesis.
A recent study by Silvester et al. found that a conserved quorum sensing signalling pathway regulates interspecies crosstalk in trypanosome co-infections and provided novel insights into trypanosome virulence and transmission.
