Phenoloxidases and cytotoxicity in ascidians: an overview [PDF]
Phenoloxidases (POs) belong to a family of copper-containing proteins (including also hemocyanins) widely distributed among invertebrates. They are able to convert polyphenols to quinones and induce cytotoxicity through the production of reactive oxygen species, a fundamental event in many immune responses.

In an invasive beetle–fungus complex, the mutualist Leptographium procerum induces host HSP83 and modulates Toll‐dependent antifungal immunity. HSP83 mediates two‐tiered control by associating with selected fungal recognition receptors and restraining Dorsal‐driven antimicrobial peptide transcription.

Guidelines for Immunomodulatory Assays of Food Bioactives on Drosophila melanogaster Model
Guidelines are proposed for evaluating the immunomodulatory effects of food bioactives in Drosophila melanogaster, involving treatment with bioactives, pathogen preparation, infection routes, and immune response assessment. This model highlights the conserved mechanisms of cellular and humoral immunity for studying host‐microbe interactions.

Males are worse mothers: Comparing care patterns in a facultatively caring beetle
Why should biparental care exist if offspring fare just as well when only one parent is present? In the facultatively dependent burying beetle, Nicrophorus vespilloides, manipulating environmental quality reveals that biparental care benefits offspring in form of lower personal immune requirement and parents in term of weight gain.

Microbiome‐mediated immunity: Limited support from the gazelle dung beetle
Digitonthophagus gazella rely on a maternally inherited microbiome passed across generations via a maternal faecal pellet called the pedestal. We experimentally manipulated the presence of the pedestal, providing it to some individuals while withholding it from others to determine how pedestal microbiota may affect beetle immune potential.
