Bovine lactoferrin-induced CCL1 expression involves distinct receptors in monocyte-derived dendritic cells and their monocyte precursors

Lactoferrin (LF) exhibits a wide range of immunomodulatory activities including modulation of cytokine and chemokine secretion. In this study, we demonstrate that bovine LF (bLF) up-modulates, in a concentration- and time-dependent manner, CCL1 secretion in monocytes (Mo) at the early stage of differentiation toward dendritic cells (DCs), and in fully differentiated immature Mo-derived DCs...

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...

Background: The development of a vaccine against HIV/AIDS capable of preventing virus infection has been hampered by the HIV envelope (Env) heterogeneity that makes it difficult to induce neutralizing antibodies against Env proteins from different HIV clades. Several studies have indicated that gp120 Env protein sequence tends to change considerably during the course of HIV disease which...

A bispecific immunotweezer prevents soluble PrP oligomers and abolishes prion toxicity

Bardelli, Marco ; Frontzek, Karl ; Simonelli, Luca ; Hornemann, Simone ; Pedotti, Mattia ; Mazzola, Federica ; Carta, Manfredi ; Eckhardt, Valeria ; D’Antuono, Rocco ; Virgilio, Tommaso ; González, Santiago F. ; Aguzzi, Adriano ; Varani, Luca

Antibodies to the prion protein, PrP, represent a promising therapeutic approach against prion diseases but the neurotoxicity of certain anti-PrP antibodies has caused concern. Here we describe scPOM-bi, a bispecific antibody designed to function as a molecular prion tweezer. scPOM-bi combines the complementarity-determining regions of the neurotoxic antibody POM1 and the neuroprotective...

The protein disulfide isomerase ERp57 regulates the steady-state levels of the prion protein

Torres, Mauricio ; Medinas,Danilo B. ; Matamala, José Manuel ; Woehlbier, Ute ; Cornejo, Víctor Hugo ; Solda, Tatiana ; Andreu, Catherine ; Rozas, Pablo ; Matus, Soledad ; Muñoz, Natalia ; Vergara, Carmen ; Cartier, Luis ; Soto, Claudio ; Molinari, Maurizio ; Hetz, Claudio

Although the accumulation of a misfolded and protease-resistant form of the prion protein (PrP) is a key event in Prion pathogenesis, the cellular factors involved in its folding and quality control are poorly understood. PrP is a glycosylated and disulfide-bonded protein synthesized at the endoplasmic reticulum (ER). The ER foldase ERp57 (also known as Grp58) is highly expressed in the brain...
