Immunology and Infection

Direct Observation of Phagocytosis and NET-formation by Neutrophils in Infected Lungs using 2-photon Microscopy

Mike Hasenberg¹, Anja Köhler¹, Susanne Bonifatius¹, Andreas Jeron², Matthias Gunzer¹

¹Institute for Molecular and Clinical Immunology, Otto-von-Guericke University Magdeburg, ²Department of Immunoregulation, Helmholtz Center for Infection Research

We show, how to use 2-photon microscopy for the observation of the dynamics of neutrophil granulocytes in infected lungs while they phagocytose pathogens or produce neutrophil extracellular traps (NETs).

Flow Cytometric Isolation of Primary Murine Type II Alveolar Epithelial Cells for Functional and Molecular Studies

Marcus Gereke^1,2, Andrea Autengruber^1,2, Lothar Gröbe³, Andreas Jeron², Dunja Bruder^1,2, Sabine Stegemann-Koniszewski¹

¹Research Group Immune Regulation, Helmholtz Centre for Infection Research, ²Research Group Infection Immunology, Institute of Medical Microbiology, Otto-von-Guericke University , ³Department of Experimental Immunology, Helmholtz Centre for Infection Research

We describe the rapid isolation of primary murine type II alveolar epithelial cells (AECII) by flow cytometric negative selection. These AECII show high viability and purity and are suitable for a wide range of functional and molecular studies regarding their role in respiratory conditions such as autoimmune or infectious diseases.

Quantitative Visualization of Leukocyte Infiltrate in a Murine Model of Fulminant Myocarditis by Light Sheet Microscopy

Linda Männ¹, Anika Klingberg², Matthias Gunzer², Mike Hasenberg³

¹Department of Translational Skin Cancer Research, University of Duisburg/Essen, ²Institute for Experimental Immunology and Imaging, University of Duisburg/Essen, ³Imaging Center Essen, Electron Microscopy Unit, University Hospital of Essen

Here, we describe a light-sheet microscopy approach to visualize the cardiac CD45⁺ leukocyte infiltrate in a murine model of aseptic fulminant myocarditis, which is induced by the intratracheal diphtheria toxin treatment of CD11c.DTR mice.

A Guide to Concentration Alternating Frequency Response Analysis of Fuel Cells

Antonio Sorrentino¹, Kai Sundmacher^1,2, Tanja Vidaković-Koch¹

¹Max Planck Institute for Dynamics of Complex Technical Systems, ²Process Systems Engineering, Otto-von-Guericke University Magdeburg

We present a protocol for concentration alternating frequency response analysis of fuel cells, a promising new method of studying fuel cell dynamics.

We describe a protocol for the chemical conjugation of the model antigen ovalbumin to an endocytosis receptor-specific antibody for in vivo dendritic cell targeting. The protocol includes purification of the antibody, chemical conjugation of the antigen, as well as purification of the conjugate and the verification of efficient conjugation.
