Glycan heterogeneity as a cause of the persistent fraction in HIV-1 neutralization

Philippe Colin, Aleksandar Antanasijevic

Neutralizing antibodies (NAbs) to multiple epitopes on the HIV-1-envelope glycoprotein (Env) have been isolated from infected persons. The potency of NAbs is measured more often than the size of the persistent fraction of infectivity at maximum neutralizat ...

Surface engineering of T cells with polymer nanoparticles to enhance drug delivery to the brain

Markus Schuster

Firstly, this thesis presents the in vivo evaluation of a previously developed model system that utilizes CD4+ TE/M cells decorated with up to 100 polystyrene based nanoparticles per cell by maleimide thiol conjugation. These nanoparticle T-cell conjugates ...

Patchy Amphiphilic Dendrimers Bind Adenovirus and Control Its Host Interactions and in Vivo Distribution

Francesco Stellacci, Weina Liu

The surface of proteins is heterogeneous with sophisticated but precise hydrophobic and hydrophilic patches, which is essential for their diverse biological functions. To emulate such distinct surface patterns on macromolecules, we used rigid spherical syn ...

Oxidation-sensitive polymersomes as vaccine nanocarriers enhance humoral responses against Lassa virus envelope glycoprotein

Jeffrey Alan Hubbell, Marcela Rincón-Restrepo, Melody Swartz, Sachiko Hirosue, Clara Galan Navarro, Stefan Kunz

Lassa virus (LASV) causes severe hemorrhagic fever with high mortality, yet no vaccine currently exists. Antibodies targeting viral attachment proteins are crucial for protection against many viral infections. However, the envelope glycoprotein (GP) 1 of L ...

Evaluation of oxidation-sensitive polymersomes as vaccine nanocarriers to enhance humoral responses against arenavirus envelope glycoproteins

Clara Galan Navarro

Vaccines currently represent one of the most effective means to control and prevent infectious diseases affecting humans and animals and have dramatically improved public health, quality of life, and life expectancy. Over the last years several conceptual ...

Pathogen-free husbandry conditions alleviate behavioral deficits and neurodegeneration in AD10 anti-NGF mice

Maria del Carmen Sandi Perez, Daniel Constam, Stamatina Tzanoulinou, Séverine Marguerite Urfer

It has been suggested that systemic infection, occurring during aging and chronic neurodegenerative diseases, can evoke an immune response that aggravates the progression of neurodegeneration and cognitive decline. It has been shown that the AD11 neurodege ...

Immune Engineering Via Differential Antigen Carriers and Co-Stimulatory Molecules

Jackson Eby

There is an increasing clinical need for vaccines capable of enhancing antigen-specific immune responses and treatments that can induce immunological tolerance toward a single antigen. Here we explore two platforms to enhance either immunization or toleriz ...

Probing Odorant-Mediated Receptor Activation

Olivia Baud

Molecular interactions of odorants with their olfactory receptors (ORs) are of central importance for the mammalian olfactory system to detect and discriminate a large variety of odors with a limited set of receptors. How a particular OR binds and distingu ...

Valproic acid enhances recombinant mRNA and protein levels in transiently transfected Chinese hamster ovary cells

Florian Maria Wurm, David Hacker, Lucia Baldi Unser, Sarah Wulhfard

Valproic acid (VPA) is a small molecule that inhibits histone deacetylase activity. Here we report that VPA increases recombinant mRNA and protein levels in transiently transfected CHO DG44 cells. In the presence of VPA, transient recombinant antibody yiel ...
