Evolution of g-type lysozymes in metazoa: insights into immunity and digestive adaptations [PDF]

Frontiers in Cell and Developmental Biology
Exploring the evolutionary dynamics of lysozymes is critical for advancing our knowledge of adaptations in immune and digestive systems. Here, we characterize the distribution of a unique class of lysozymes known as g-type, which hydrolyze key components

Early Animal Origin of BACE1 APP/Aβ Proteolytic Function [PDF]

Biology
Alzheimer’s disease is characterized, in part, by the accumulation of β-amyloid (Aβ) in the brain. Aβ is produced via the proteolysis of APP by BACE1 and γ-secretase.

From ctenophores to scyphozoans: parasitic spillover of a burrowing sea anemone [PDF]

Scientific Reports
Most host-parasite associations are explained by phylogenetically conservative capabilities for host utilization, and therefore parasite switches between distantly related hosts are rare.

Cambrian comb jellies from Utah illuminate the early evolution of nervous and sensory systems in ctenophores

iScience, 2021
Summary: Ctenophores are a group of predatory macroinvertebrates whose controversial phylogenetic position has prompted several competing hypotheses regarding the evolution of animal organ systems. Although ctenophores date back at least to the Cambrian,

A late-surviving stem-ctenophore from the Late Devonian of Miguasha (Canada)

Scientific Reports, 2021
Like other soft-bodied organisms, ctenophores (comb jellies) produce fossils only under exceptional taphonomic conditions. Here, we present the first record of a Late Devonian ctenophore from the Escuminac Formation from Miguasha in eastern Canada. Based
