Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis
FEBS Letters, EarlyView.Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Serum amyloid P aids complement-mediated immunity to Streptococcus pneumoniae [PDF]
, 2007 The physiological functions of the acute phase protein serum amyloid P (SAP) component are not well defined, although they are likely to be important, as no natural state of SAP deficiency has been reported.

PLoS Pathogens, 2019 Ecotin is a serine protease inhibitor produced by hundreds of microbial species, including pathogens. Here we show, that ecotin orthologs from Escherichia coli, Yersinia pestis, Pseudomonas aeruginosa and Leishmania major are potent inhibitors of MASP-1 ...

Activation of the alternative complement pathway by Sporothrix schenckii [PDF]
Infection and Immunity, 1986 We studied the activation of complement by Sporothrix schenckii yeast cells. Total complement activity, and the effect of various activators on this activity, were assayed on aliquots of fresh nonimmune human serum with and without prior treatment with chelators.

Antimicrobial peptides and complement in neonatal hypoxia-ischemia induced brain damage [PDF]
, 2015 Hypoxic-ischemic encephalopathy (HIE) is a clinical condition in the neonate, resulting from oxygen deprivation around the time of birth. HIE affects 1-5/1000 live births worldwide and is associated with the development of neurological deficits ...

Design and analysis strategies for robust microbiome ageing research
FEBS Letters, EarlyView.The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Characterization and functional analysis of mouse Ficolin B [PDF]
, 2012 The innate immune system contributes day by day to the elimination of invading pathogens. The lectin pathway of the complement system is initiated when mannose-binding-lectin (MBL) or ficolins interact with MASP-2.

Bloqueo del complemento: promesas terapéuticas y retos pendientes en la práctica clínica
NefrologíaResumen: La comprensión del complemento en las glomerulopatías ha avanzado notablemente, mostrando que este sistema, más allá de la inmunidad innata, es un mediador clave del daño renal en un amplio espectro de nefropatías, desde las mediadas por ...
