Breast milk microbiota: A review of the factors that influence composition

Zimmermann, Petra ; Curtis, Nigel

In: Journal of Infection, 2020, vol. 81, no. 1, p. 17–47

Breastfeeding is associated with considerable health benefits for infants. Aside from essential nutrients, immune cells and bioactive components, breast milk also contains a diverse range of microbes, which are important for maintaining mammary and infant health. In this review, we summarise studies that have investigated the composition of the breast milk microbiota and factors that might...

The effect of maternal immunisation during pregnancy on infant vaccine responses

Zimmermann, Petra ; Perrett, Kirsten P. ; Messina, Nicole L. ; Donatha, Susan ; Ritz, Nicole ; Klis, Fiona R. M. van der ; Curtis, Nigel

In: EClinicalMedicine, 2019, vol. 13, p. 21–30

Immunisation during pregnancy to protect infants against tetanus, pertussis and influenza is recommended in many countries. However, maternal antibodies can interfere with infant vaccine responses. We investigated the effect of antenatal diphtheria-tetanus-acellular pertussis (dTpa) and trivalent inactivated influenza (TIV) immunisation on specific and heterologous antibody responses to...

Antimicrobial effects of antipyretics

Zimmermann, Petra ; Curtis, Nigel

In: Antimicrobial Agents and Chemotherapy, 2017, vol. 61, no. 4, p. -

Antipyretics are some of the most commonly used drugs. Since they are often coadministered with antimicrobial therapy, it is important to understand the interactions between these two classes of drugs. Our review is the first to summarize the antimicrobial effects of antipyretic drugs and the underlying mechanisms involved. Antipyretics can inhibit virus replication, inhibit or promote...

The immunomodulatory effects of macrolides - a systematic review of the underlying mechanisms

Zimmermann, Petra ; Ziesenitz, Victoria C. ; Curtis, Nigel ; Ritz, Nicole

In: Frontiers in Immunology, 2018, vol. 9, p. -

The mechanisms underlying the non-antimicrobial immunomodulatory properties of macrolides are not well understood.Objectives: To systematically review the evidence for the immunomodulatory properties of macrolides in humans and to describe the underlying mechanism and extent of their influence on the innate and adaptive immune system.Methods: A systematic literature search was done in MEDLINE...

Infected cephalhaematoma in a five-week-old infant - case report and review of the literature

Zimmermann, Petra ; Duppenthaler, Andrea

In: BMC Infectious Diseases, 2016, vol. 16, no. 1, p. 636

A cephalhaematoma is usually a benign condition which resolves spontaneously. Nevertheless, there is a small risk of primary or secondary infection and diagnosis of this condition is challenging. The purpose of this article is to summarise risk factors, clinical criteria, pathogenesis, appropriate investigations and treatment methods for infected cephalhaematomas in infants.Case presentation:...

Cell-Permeant and photocleavable chemical inducer of dimerization

Zimmermann, Mirjam ; Cal, Ruben ; Janett, Elia ; Hoffmann, Viktor ; Bochet, Christian G. ; Constable, Edwin ; Beaufils, Florent ; Wymann, Matthias P.

In: Angewandte Chemie International Edition, 2014, vol. 53, no. 18, p. 4717–4720

Chemical inducers of dimerization (CIDs) have been developed to orchestrate protein dimerization and translocation. Here we present a novel photocleavable HaloTag- and SNAP-tag-reactive CID (MeNV-HaXS) with excellent selectivity and intracellular reactivity. Excitation at 360 nm cleaves the methyl-6-nitroveratryl core of MeNV-HaXS. MeNV-HaXS covalently links HaloTag- and SNAP-tag fusion...
