Single-cell RNA sequencing analysis of shrimp immune cells identifies macrophage-like phagocytes

open access: yeseLife, 2022
Despite the importance of innate immunity in invertebrates, the diversity and function of innate immune cells in invertebrates are largely unknown. Using single-cell RNA-seq, we identified prohemocytes, monocytic hemocytes, and granulocytes as the three ...

Host-selected mutations converging on a global regulator drive an adaptive leap towards symbiosis in bacteria [PDF]

open access: yes, 2017
Host immune and physical barriers protect against pathogens but also impede the establishment of essential symbiotic partnerships. To reveal mechanisms by which beneficial organisms adapt to circumvent host defenses, we experimentally evolved ...

Iflaviruses in arthropods: when small is mighty

open access: yesInsect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Isolation and Infection of Drosophila Primary Hemocytes

open access: yesBio-Protocol, 2017
Phagocytosis of invading pathogens and their subsequent clearance in lysosomes is important for organismal fitness. We have devised the following protocol to extract phagocytic hemocytes from wild-type and mutant Drosophila larvae and infect the isolated

Single cell RNA sequencing reveals hemocyte heterogeneity in Biomphalaria glabrata: Plasticity over diversity

open access: yesFrontiers in Immunology, 2022
The freshwater snail Biomphalaria glabrata is an intermediate host of Schistosoma mansoni, the agent of human intestinal schistosomiasis. However, much is to be discovered about its innate immune system that appears as a complex black box, in which the ...

Hemocytes of Mosquito Larvae

open access: yesThe Florida Entomologist, 1978
Plasmatocytes, oenocytoids, and granular hemocytes inside the anal papillae of larval Culex tarsalis Coquillett, Psorophora ciliata (F.), Aedes aegypti (L.) and A. atlanticus Dyar and Knab were described following examinations by light and electron microscopy.

Is there a causal association between genotoxicity and the imposex effect? [PDF]

open access: yes, 2006
There is a growing body of evidence that indicates common environmental pollutants are capable of disrupting reproductive and developmental processes by interfering with the actions of endogenous hormones.

Calcitonin‐like diuretic hormone influences reproduction in adult female Rhodnius prolixus

open access: yesInsect Science, EarlyView.
Highlights • CT/DH‐like immunoreactivity is present in female reproductive tissues • CT/DH receptor transcripts are expressed in the fat body and ovaries • RNAi knockdown of CT/DH receptors reduces egg number and hatching rate • Rhopr‐CT/DH increases RhoprVg1 and RhoprVgR expression in ovaries in vitro • Rhopr‐CT/DH stimulates oviduct contractions in a

Hemocyte-hemocyte adhesion by granulocytes is associated with cellular immunity in the cricket, Gryllus bimaculatus [PDF]

open access: yesScientific Reports, 2019
AbstractIn this study, more than 1,000 cricket (Gryllus bimaculatus) hemocytes were classified based on their size and morphology. These hemocytes were classified into six types: granulocytes, plasmatocytes, prohemocytes, spherulocytes, coagulocytes, and oenocytoids.

The selectivity and specificity of autophagy in drosophila [PDF]

open access: yes, 2012
Autophagy is a process of cellular self-degradation and is a major pathway for elimination of cytoplasmic material by the lysosomes. Autophagy is responsible for the degradation of damaged organelles and protein aggregates and therefore plays a ...
