Aedes aegypti; DNA; DNA replication; Drosophila melanogaster; immune response; innate immunity; invertebrates; midgut; oocytes; pathogens; tissues; virion
Abstract:
... Priming is the conceptual term defining memory phenomenon in innate immune response. Numerous examples of enhanced secondary immune response have been described in diverse taxa of invertebrates; which naturally lacks memory response. In mosquitoes, a previous non-lethal challenge with some specific pathogens modify their immune response against the same microorganism; developing an improved antimi ...

Baculoviridae; Bombyx mori; DNA damage; DNA replication; Lymantria dispar; Spodoptera frugiperda; apoptosis; enzyme activity; genes; immunity; pathogenesis; proteinases
Abstract:
... Apoptosis is important in antiviral immunity and affects viral multiplication and pathogenesis. Here, we showed that Bombyx mori cells transiently expressing B. mori homolog of the tumor suppressor p53 (Bm-p53) protein underwent apoptosis accompanied by elevated caspase-3-like protease activity and processing of B. mori Dronc (Bm-Dronc). RNAi-mediated silencing of bm-p53 expression, which signific ...

Abstract:
... In hematophagous insects, the midgut is a fundamental barrier against infections and limits the development and transmission of pathogens. However, in mosquitoes, cell differentiation, proliferation, and cell cycle process in the midgut have not been characterized. Here we provide evidence of how cell cycle progression occurs in the newly emerged Anopheles albimanus mosquito midgut and describing ...

Abstract:
... Immunological priming in insects is defined as a previous contact with non-virulent pathogens, which induces protection after a second virulent infection. The mechanism of this process is not well understood. We have observed midgut DNA synthesis (endoreplication) in Plasmodium berghei exposure mosquitoes (primed) and after the immune challenge, which could be an essential component of the priming ...

Abstract:
... In invertebrates, “immunological priming” is considered as the ability to acquire a protective (adaptive) immune response against a pathogen due to previous exposure to the same organism. To date, the mechanism by which this type of adaptive immune response originates in insects is not well understood. In the Anopheles albimanus - Plasmodium berghei model, a DNA synthesis that probably indicates a ...

Abstract:
... Invertebrates rely on the efficient innate immune mechanisms against invaders, in which the continuous production of hemocytes (hematopoiesis) is indispensable. In the present study, the hematopoietic tissue (HPT) from Chinese mitten crab Eriocheir sinensis was identified and characterized. It was a thin and non-transparent sheet located at the dorsolateral side of the stomach, which was composed ...

Abstract:
... Increasing evidences have demonstrated that the invertebrate gill is a predominant tissue participating in the immune response during pathogen challenge. In the present study, the hematopoiesis and immune activities in gill of Pacific oyster Crassostrea gigas were investigated. Stem-like cells with big nuclei and thin cytoplasm were found in the tubules of gill filaments, where DNA synthesis is ac ...
