Insect Serosa: A Head Line in Comparative Developmental Genetics
نویسنده
چکیده
A recent study reveals specific functions of Hox3/zerknüllt (zen) in the extraembryonic and embryonic primordia of the red flour beetle, Tribolium castaneum. The results shed light on the functional evolution of bicoid, a zen paralogue of higher flies, which determines anterior body parts.

Immune competence in insect eggs depends on the extraembryonic serosa.
Innate immunity is common to all metazoans and serves as a first line of defense against pathogens. Although the immune response of adult and larval insects has been well characterized, it remains unknown whether the insect egg is able to mount an immune response. Contrary to Drosophila, Tribolium eggs develop an extraembryonic epithelium, the serosa. Epithelia are well known for their ability ...
متن کاملConstruction of a Recombinant Bacmid DNA to Express Influenza Virus Matrix Protein1 (M1) in Insect Cell Line
Background and Aims: Virus-like particles (VLPs) have been suggested to be a promising recombinant vaccine approach. Several studies have reported that the influenza VLPs produced in insect cells is an effective vaccine candidate. Due to crucial role of matrix M1 protein in assembly and budding of Influenza particles, in all VLPs structures, M1 protein have been considered as a main component. ...
متن کاملBaculoviral Expression of Influenza A Virus (H1N1 New Caledonia) Neuraminidase in Insect Cells
Background and Aims: Each year, the influenza virus causes moderate to severe infections with a high prevalence throughout the world. Accordingly, an influenza vaccine that ensures protection with only a single dose would be a much more cost effective approach to influenza prophylaxis. Generation of Influenza non-replicating virus-like particles (VLP) in baculoviral expression system is an attr...
متن کاملThe extraembryonic serosa protects the insect egg against desiccation.
Insects have been extraordinarily successful in occupying terrestrial habitats, in contrast to their mostly aquatic sister group, the crustaceans. This success is typically attributed to adult traits such as flight, whereas little attention has been paid to adaptation of the egg. An evolutionary novelty of insect eggs is the serosa, an extraembryonic membrane that enfolds the embryo and secrete...
متن کاملExtraembryonic development in insects and the acrobatics of blastokinesis.
Extraembryonic development is familiar to mouse researchers, but the term is largely unknown among insect developmental geneticists. This is not surprising, as the model system Drosophila melanogaster has an extremely reduced extraembryonic component, the amnioserosa. In contrast, most insects retain the ancestral complement of two distinct extraembryonic membranes, amnion and serosa. These mem...
