  eLife Assessment

  This important work provides a fresh perspective on merozoite surface biology and its implications for vaccine design, challenging the prevailing dogma that MSPs are indispensable invasion engines. The revised manuscript strengthens the compelling evidence that, although MSP2 is dispensable for parasite growth, it acts as an immune modulator of AMA1. While the study is commendable for its use of state-of-the-art technologies and the skillful application of monoclonal antibodies, the inclusion of human monoclonal antibodies and electron microscopy imaging approaches would significantly add to the importance of these observations. Overall, this work will be of considerable interest to investigators studying Plasmodium biology and vaccine development.

  eLife Assessment

  This important study convincingly demonstrates how bacterial cells can modulate outer membrane-peptidoglycan tethering by expressing two different Lpp homologs with distinct cross-linking efficiencies, revealing that Salmonella typhimurium LppB forms disulfide-based homodimers (or heterotrimers with Lpp when present) and is covalently attached to peptidoglycan primarily via the L,D-transpeptidase LdtB at residue K58. The evidence supporting the authors' claims is solid, including the regulatory role of LppB dimerization for its abundance in E. coli and its ability to inhibit Lpp/A crosslinking to peptidoglycan, although additional analysis and quantification of muropeptides in wild-type E. coli overexpressing LppB would further strengthen the findings. Overall, the work will be of great interest to microbiologists studying cell envelope biogenesis.
