Immunology, Volume 167, Issue 4, Page 622-639, December 2022., 2022 Proposed biophysical model. Abstract Age‐associated changes in T‐cell function play a central role in immunosenescence. The role of aging in the decreased T‐cell repertoire, primarily because of thymic involution, has been extensively studied. However, increasing evidence indicates that aging also modulates the mechanical properties of cells and the ...

A novel fluorescence and DNA combination for versatile, long‐term marking of mosquitoes
Methods in Ecology and Evolution, Volume 12, Issue 6, Page 1008-1016, June 2021., 2021 Abstract Current mark–release–recapture methodologies are limited in their ability to address complex problems in vector biology, such as studying multiple groups overlapping in space and time. Additionally, limited mark retention, reduced post‐marking survival and the large effort in marking, collection and recapture all complicate effective insect ...
