Rickettsia parkeri hijacks tick hemocytes to manipulate cellular and humoral transcriptional responses

open access: yesFrontiers in Immunology, 2023
IntroductionBlood-feeding arthropods rely on robust cellular and humoral immunity to control pathogen invasion and replication. Tick hemocytes produce factors that can facilitate or suppress microbial infection and pathogenesis. Despite the importance of

Immunological resilience of a freshwater Indian mollusc during aestivation and starvation

open access: yesAquaculture Reports, 2016
Freshwater snail, Pila globosa is an edible mollusc which bears commercial and ethnomedicinal significance. During environmental aridity, P. globosa aestivates deep into the soil for four to five months.

Distinct Roles of Hemocytes at Different Stages of Infection by Dengue and Zika Viruses in Aedes aegypti Mosquitoes

open access: yesFrontiers in Immunology, 2021
Aedes aegypti mosquitoes are vectors for arboviruses of medical importance such as dengue (DENV) and Zika (ZIKV) viruses. Different innate immune pathways contribute to the control of arboviruses in the mosquito vector including RNA interference, Toll ...

Identification and Characterization of the Lipid Transport System in the Tarantula Grammostola rosea [PDF]

open access: yes, 2015
Lipids due to its hydrophobic nature are transported in the hemolymph mainly by lipoproteic fractions. In the present work we studied the lipoproteic fractions present in the hemolymph of the spider Grammostola rosea.

Autophagy occurs upstream or parallel to the apoptosome during histolytic cell death [PDF]

open access: yes, 2006
Histolysis refers to a widespread disintegration of tissues that is morphologically distinct from apoptosis and often associated with the stimulation of autophagy. Here, we establish that a component of the apoptosome, and pivotal regulator of apoptosis,

In vivo detection of lamellocytes in Drosophila melanogaster. [PDF]

open access: yes, 2009
Drosophila has recently become a powerful model organism for studies of innate immunity. The cellular elements of innate immunity in Drosophila, the hemocytes, have been characterized by morphological criteria, molecular markers, and cell-type-specific ...

Differential lectin labelling of circulating hemocytes from Biomphalaria glabrata and Biomphalaria tenagophila resistant or susceptible to Schistosoma mansoni infection

open access: yesMemorias do Instituto Oswaldo Cruz, 2006
Lectins/carbohydrate binding can be involved in the Schistosoma mansoni recognition and activation of the Biomphalaria hemocytes. Therefore, expression of lectin ligands on Biomphalaria hemocytes would be associated with snail resistance against S ...

Transglutaminase 3 negatively regulates immune responses on the heart of the mosquito, Anopheles gambiae

open access: yesScientific Reports, 2022
The immune and circulatory systems of insects are functionally integrated. Following infection, immune cells called hemocytes aggregate around the ostia (valves) of the heart.

Variation of NimC1 expression in Drosophila stocks and transgenic strains. [PDF]

open access: yes, 2013
The NimC1 molecule has been described as a phagocytosis receptor, and is being used as a marker for professional phagocytes, the plasmatocytes, in Drosophila melanogaster.
