Trypanosoma cruzi P21 Is a Pleiotropic Protein That Is Involved in Parasite Host Cell Invasion and Intracellular Parasitism

MicrobiologyOpen, Volume 14, Issue 6, December 2025.
This study reveals the pleiotropic role of Trypanosoma cruzi P21 protein in the low‐virulence G strain. P21 knockout significantly impairs parasite invasion, intracellular multiplication, and egress in vitro. In vivo, P21 deficiency leads to reduced cardiac tissue parasitism, suggesting its role in establishing and maintaining silent infections.

Temporal field phenomics of transgenic maize events subjected to drought stress: Cross‐validation scenarios and machine learning models

The Plant Phenome Journal, Volume 8, Issue 1, December 2025.
Abstract Global climate change has driven breeding programs to develop abiotic stress‐resilient plant varieties. Traditionally, assessing drought resilience involves labor‐intensive and time‐consuming processes. This study used an unmanned aerial system (UAS) to predict key phenotyping traits in maize (Zea mays L.) and monitor plant response to drought

New Evidence of TLR4 and TLR9 Variants Influencing Parasitaemia and Symptoms of Plasmodium vivax Infection

International Journal of Immunogenetics, Volume 52, Issue 6, Page 371-378, December 2025.
ABSTRACT Toll‐like receptors (TLRs) induce the production of pro‐inflammatory cytokines and regulate the immune response to Plasmodium vivax infection. Genetic variants of TLRs are associated with susceptibility and severity of malaria in different populations. This study aimed to evaluate the association between polymorphisms in TLR1, TLR4, TLR7, TLR8,
