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:...

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

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...

Biological sex influences antibody responses to routine vaccinations in the first year of life

Zimmermann, Petra ; Perrett, Kirsten P. ; Ritz,  Nicole ; Flanagan, Katie L. ; Robins-Browne, Roy ; Klis, Fiona R. M. van der ; Curtis, Nigel ; the MIS BAIR group

In: Acta Paediatrica, 2019, p. -

Aim We investigated the effect of early-life factors, namely sex, delivery mode, feeding method and antibiotic exposure, on antibody responses to routine vaccinations administered during the first year of life. Methods One and seven months after the primary course of routine vaccines and 1 month after routine vaccines at 12 months of age, antibodies against 26 vaccine antigens were measured...

Large-scale analysis of the mycoplasma bovis genome identified non-essential, adhesion- and virulence-related genes

Josi, Christoph ; Bürki, Sibylle ; Vidal, Sara ; Dordet-Frisoni, Emilie ; Citti, Christine ; Falquet, Laurent ; Pilo, Paola

In: Frontiers in Microbiology, 2019, vol. 10, p. -

Mycoplasma bovis is an important pathogen of cattle causing bovine mycoplasmosis. Clinical manifestations are numerous, but pneumonia, mastitis, and arthritis cases are mainly reported. Currently, no efficient vaccine is available and antibiotic treatments are not always satisfactory. The design of new, efficient prophylactic and therapeutic approaches requires a better understanding of the...

Therapeutic efficacy of antibodies lacking FcγR against lethal dengue virus infection is due to neutralizing potency and blocking of enhancing antibodies

Williams, Katherine L. ; Sukupolvi-Petty, Soila ; Beltramello, Martina ; Johnson, Syd ; Sallusto, Federica ; Lanzavecchia, Antonio ; Diamond, Michael S. ; Harris, Eva

In: Plos pathogens, 2013, vol. 9, no. 2, p. e1003157

Dengue hemorrhagic fever and dengue shock syndrome (DHF/DSS) are life-threatening complications following infection with one of the four serotypes of dengue virus (DENV). At present, no vaccine or antiviral therapies are available against dengue. Here, we characterized a panel of eight human or mouse-human chimeric monoclonal antibodies (MAbs) and their modified variants lacking effector...

Systems analysis of MVA-C induced immune response reveals its significance as a vaccine candidate against HIV/AIDS of clade C

Gómez, Carmen Elena ; Perdiguero, Beatriz ; Jiménez, Victoria ; Filali-Mouhim, Abdelali ; Ghneim, Khader ; Haddad, Elias K. ; Quakkerlaar, Esther D. ; Delaloye, Julie ; Harari, Alexandre ; Roger, Thierry ; Dunhen, Thomas ; Sékaly, Rafick P. ; Melief, Cornelis J. M. ; Calandra, Thierry ; Sallusto, Federica ; Lanzavecchia, Antonio ; Wagner, Ralf ; Pantaleo, Giuseppe ; Esteban, Mariano

Based on the partial efficacy of the HIV/AIDS Thai trial (RV144) with a canarypox vector prime and protein boost, attenuated poxvirus recombinants expressing HIV-1 antigens are increasingly sought as vaccine candidates against HIV/AIDS. Here we describe using systems analysis the biological and immunological characteristics of the attenuated vaccinia virus Ankara strain expressing the HIV-1...

In-depth analysis of the antibody response of individuals exposed to primary dengue virus infection

Alwis, Ruklanthi de ; Beltramello, Martina ; Messer, William B. ; Sukupolvi-Petty, Soila ; Wahala, Wahala M. P. B. ; Kraus, Annette ; Olivarez, Nicholas P. ; Pham, Quang ; Brian, James ; Tsai, Wen-Yang ; Wang, Wei-Kung ; Halstead, Scott ; Kliks, Srisakul ; Diamond, Michael S. ; Baric, Ralph ; Lanzavecchia, Antonio ; Sallusto, Federica ; Silva, Aravinda M. de

In: Plos neglected tropical diseases, 2011, vol. 5, no. 6, p. e1188

Humans who experience a primary dengue virus (DENV) infection develop antibodies that preferentially neutralize the homologous serotype responsible for infection. Affected individuals also generate cross-reactive antibodies against heterologous DENV serotypes, which are non-neutralizing. Dengue cross-reactive, non-neutralizing antibodies can enhance infection of Fc receptor bearing cells and,...
