The authors also provided comparative analysis to single-cell studies in other insect systems, highlighting important similarities and differences between mosquitoes and other insects. The study found mosquito hemocytes show greater complexity than previously thought, evidence of cell differentiation, and that some cells may even undergo a maturation process. The new study utilized single-cell RNA sequencing, a relatively new technique that allows researchers to examine the cellular messages within individual cells, to characterize mosquito immune cells, known as hemocytes.
“These experiments lay the foundation for a better understanding of how these immune cells function that could lead to a future when humans are able to make mosquitoes unable to transmit disease,” Smith said. It’s a field of study that has remained poorly understood due to the lack of genetic tools, said Ryan Smith, an associate professor of entomology at Iowa State University and lead author of the study.
Immune cells play a central role in the immune response of mosquitoes toward malaria parasites and viruses after these pathogens are taken up upon feeding on an infected person. AMES, Iowa – A new study that details mosquito immune cells could shed light on the insect immune system and how mosquitoes transmit parasites that cause malaria.Ī new study, published recently in the peer-reviewed scientific journal eLife, identifies several new forms of mosquito immune cells, providing new clarity into the mosquito immune system.
