Senescent T cells: Beneficial and detrimental roles

Immunological Reviews, Volume 316, Issue 1, Page 160-175, July 2023., 2023
Summary As the thymus involutes during aging, the T‐cell pool has to be maintained by the periodic expansion of preexisting T cells during adulthood. A conundrum is that repeated episodes of activation and proliferation drive the differentiation of T cells toward replicative senescence, due to telomere erosion.

Suppression of TGF‐β/Smad2 signaling by GW788388 enhances DENV‐2 clearance in macrophages

Journal of Medical Virology, Volume 94, Issue 9, Page 4359-4368, September 2022., 2022
Abstract Dengue fever, caused by the dengue virus (DENV‐1, −2, −3, and −4), affects millions of people in the tropical and subtropical regions worldwide. Severe dengue is correlated with high viraemia and cytokine storm, such as high levels of transforming growth factor‐β1 (TGF‐β1) in the patient's serum.

Effects of anti‐Leishmania compounds in the behavior of the sand fly vector Lutzomyia longipalpis

Pest Management Science, Volume 78, Issue 7, Page 2792-2805, July 2022., 2022
Sugar baits can be used to block the development of Leishmania parasites inside the gut of the vector, adult female sand flies. In this work, we screened a series of synthetic compounds and showed that three of them are suitable for the future development of baits targeting the Leishmania parasites inside the sand fly Lutzomyia longipalpis.

Cryptococcus extracellular vesicles properties and their use as vaccine platforms

Journal of Extracellular Vesicles, Volume 10, Issue 10, August 2021., 2021
Abstract Whereas extracellular vesicle (EV) research has become commonplace in different biomedical fields, this field of research is still in its infancy in mycology. Here we provide a robust set of data regarding the structural and compositional aspects of EVs isolated from the fungal pathogenic species Cryptococcus neoformans, C. deneoformans and C.

Combining Well‐Tempered Metadynamics Simulation and SPR Assays to Characterize the Binding Mechanism of the Universal T‐Lymphocyte Tetanus Toxin Epitope TT830‐843

BioMed Research International, Volume 2021, Issue 1, 2021., 2021
Peptide TT830‐843 from the tetanus toxin is a universal T‐cell epitope. It helps in vaccination and induces T‐cell activation. However, the fine molecular interaction between this antigen and the major histocompatibility complex (MHC) remains unknown.
