Echinococcus granulosus sensu lato (s.l.) is a cestode parasite affecting both human and livestock health. Recombinant ectodomains of human scavenger receptors CD5 (rshCD5) and CD6 (rshCD6) were previously reported to bind its tegumental antigens and to exert prophylactic effects in a murine model of infection. Although the properties of mammalian scavenger receptors include the binding to diverse pathogen-derived structures, their interaction with helminth parasites has been scarcely explored. Therefore, we report here a search for CD5 and CD6 interactorswithin E. granulosus s.l. antigens.Mass spectrometry analysis of pull-downs fromsoluble tegumental componentswith biotinylated rshCD5 and rshCD6 resulted in 17 and 11 overrepresented interactors,
respectively, 8 of which were shared. The nteractors included previously reported protective molecules against E. granulosus s.l. and/or other helminths. Similar studies performedwith 11-mer peptides mapping to each of the three extracellular scavenger domains of CD5 and CD6 allowed an estimated molecular topology of the interactions.
In conclusion, the fact that most helminth interactors identified for rshCD5 and rshCD6 were already reported as vaccine candidates or pharmacological targets against different helminthiases, supports the view that their beneficial effects in experimental infection results from binding to multiple relevant tegumental
antigens.

Satisfaction with food-related life (SWFRL) is one component of satisfaction with life. Although researchers have identified associations between satisfaction with food-related life and specific food behaviours, it is still not clear how consumers conceptualize this complex construct. The aims of the present study were to explore consumers’
conceptualization of SWFRL, to compare how parents and adolescents in dual-headed households perceive SWFRL, and to identify aspects that would increase their SWFRL. One-hundred and sixty-four dual families
composed of mother, father, and at least one adolescent child between 10 and 17 years of age participated in the study. They completed a word association task with “Being satisfied with my food-related life” and completed
the sentence “I would be more satisfied with my food-related life if…”. Participants’ responses were aligned with the formal definition of SWFRL. References to specific foods and food characteristics were also mentioned in the
word association task. No significant differences were found between parents and adolescents in the frequency of mention of responses related to the identified categories and supra-categories, suggesting lack of differences in their conceptualization of SWFRL. Changes in eating behaviours and individuals’ resources for purchasing and preparing foods were regarded as the main factors that could increase SWFRL. Differences between family
members were found in some of the aspects associated with an increase in SWFRL. Results from this study can aid in the development of strategies for promoting changes in eating habits and increasing SWFRL, targeted at different family members.
