Functional analysis of novel microneme proteins from Plasmodium vivax blood stages identifies vaccine candidates

Arunaditya Deshmukh, Francisco José Martínez Martínez, Pailene S. Lim, Lionel Brice Feufack-Donfack, Florent Dingli, K. E. Stoll Pekin, Baura Tat, Benson Kiniboro, D. Herbert Opi, Yee-Ling Lau, Mun Yik Fong, Eun‐Taek Han, James G. Beeson, Jetsumon Sattabongkot, Ivo Mueller, , Chetan E. Chitnis

The paper identifies and characterizes two novel Plasmodium vivax merozoite proteins, PvMP45 and PvMP36, which bind reticulocyte receptors and are targets of protective antibodies, suggesting their potential as vaccine candidates.

Navigating parasite antigen genetic diversity in the design of Plasmodium vivax serological exposure markers for malaria

Paolo Bareng, Keliang Wu, Eizo Takashima, Dionne C. Argyropoulos, Lauren Smith, Myo T. Naung, Ramin Mazhari, Kael L. Schoffer, Nicholas Kiernan‐Walker, Anju Abraham, Macie Lamont, Somya Mehra, Pailene S. Lim, Jetsumon Sattabongkot, Wuelton Marcelo Monteiro, , Rhea J. Longley

This study evaluates how genetic diversity in Plasmodium vivax antigens affects serological markers for malaria exposure and finds that using multiple antigens can improve detection accuracy.

Development and validation of serological markers for detecting recent exposure to Plasmodium vivax infection

Rhea J. Longley, Michael T. White, Eizo Takashima, Jessica Brewster, Masayuki Morita, Matthias Harbers, Leanne J. Robinson, Fumie Matsuura, Shih-Jung Zoe Liu, Connie S. N. Li-Wai-Suen, Wai-Hong Tham, Julie Healer, Christele Huon, Chetan E. Chitnis, Wang Nguitragool, , Ivo Mueller

The paper identifies and validates a panel of 8 P. vivax proteins whose IgG antibody responses can detect recent exposure to P. vivax infections within the prior 9 months with 80% sensitivity and specificity.

Genetic diversity in two Plasmodium vivax protein ligands for reticulocyte invasion

Camille Roesch, Jean Popovici, Sophalai Bin, Vorleak Run, Saorin Kim, Stéphanie Ramboarina, Emma Rakotomalala, Rado Lalaina Rakotoarison, Lova Tsikiniaina Rasoloharimanana, Zo Andriamanantena, Anuj Kumar, Micheline Guillotte-Blisnick, Christèle Huon, David Serre, Chetan E. Chitnis, , Didier Ménard

The paper analyzes genetic diversity in PvDBP and PvEBP from P. vivax isolates in Cambodia and Madagascar, finding higher PvEBP copy numbers in Madagascar and evidence of diversifying selection on PvEBP.
