Turning a vulnerability into a strength
Balau, Ana; Sobral, Daniel; Medeiros, Márcia; Antunes, Sandra; de Carvalho, Maria Duarte; Morais, Inês; Carvalho, Filomena; Gomes, João PauloMalaria remains a global health challenge and despite the considerable progress made in the mortality rate, the 2025 target of the Global Technical Strategy 2016–2030 is still far from being reached. New strategies to improve patient management, prevent severe cases, and reduce deaths, are urgently needed. Exploring interactions between the malaria parasite and host red blood cells (RBCs) offers opportunities t...

Direct antimicrobial defence is provided by the syn...
Differential Gene Expression of Malaria Parasite in Response to Red Blood Cell-...
Balau, Ana; Sobral, Daniel; Abrantes, Patrícia; Santos, Inês; Mixão, Verónica; Gomes, João Paulo; Antunes, Sandra; Arez, Ana PaulaInnovative strategies to control malaria are urgently needed. Exploring the interplay between Plasmodium sp. parasites and host red blood cells (RBCs) offers opportunities for novel antimalarial interventions. Pyruvate kinase deficiency (PKD), characterized by heightened 2,3-diphosphoglycerate (2,3-DPG) concentration, has been associated with protection against malaria. Elevated levels of 2,3-DPG, a specific ma...
