Preparation of Nippostrongylus brasiliensis Larvae for the Study of Host Skin Response

Authors: Tiffany Bouchery, Gillian Coakley and Nicola L. Harris, date: 12/20/2020, view: 610, Q&A: 0

[Abstract]

Hookworms are skin penetrating parasites, however in the laboratory the hookworm model Nippostrongylus brasiliensis, the parasite is traditionally administered subcutaneously bypassing the skin (epidermis and dermis). Here, we describe two complementary approaches for infecting mice with N. brasiliensis in order to study the skin immune responses.

Surgical Induction of Endometriosis in Female Mice

Authors: Alejandra Escudero-Lara, David Cabañero and Rafael Maldonado, date: 09/20/2020, view: 1022, Q&A: 0

[Abstract] Endometriosis is a common gynecological disease characterized by the presence of endometrial tissue outside the uterine cavity. It is frequently associated with pain, infertility and a reduced quality of life, and it lacks adequate treatment. Several rodent models of endometriosis have been developed through heterologous and homologous ...

Immunohistochemistry of Kidney a-SMA, Collagen 1, and Collagen 3, in A Novel Mouse Model of Reno-cardiac Syndrome

Authors: Julius E. Kieswich, Jianmin Chen, Samira Alliouachene, Paul W. Caton, Kieran McCafferty, Christoph Thiemermann and Muhammad M. Yaqoob, date: 09/20/2020, view: 840, Q&A: 0

[Abstract] Cardiorenal syndrome defines a synergistic pathology of the heart and kidneys where failure of one organ causes failure in the other. The incidence of cardiovascular mortality caused by this syndrome, is 20 fold higher in the end stage renal disease (ESRD) population compared to the population as a whole thus necessitating the need for improved ...

Real-time in vivo Imaging of LPS-induced Local Inflammation and Drug Deposition in NF-κB Reporter Mice

Authors: Artur Schmidtchen and Manoj Puthia, date: 08/20/2020, view: 1785, Q&A: 0

[Abstract] Wound, biomaterial, and surgical infections are all characterized by a localized and excessive inflammation, motivating the development of in vivo methods focused on the analysis of local immune events. However, current inflammation models, such as the commonly used in vivo models of endotoxin-induced inflammation are based on ...

Isolation and Quantification of Extracellular DNA from Biofluids

Authors: Ľubica Janovičová, Barbora Konečná, Barbora Vlková and Peter Celec, date: 08/20/2020, view: 1378, Q&A: 0

[Abstract] Extracellular DNA is studied as a diagnostic biomarker, but also as a factor involved in the pathophysiology of several diseases due to its pro-inflammatory properties. Extracellular DNA can be extracted from plasma, urine, saliva or other biofluids using standard DNA isolation procedures and specialized commercial kits. Sample preparation for ...

RNA Extraction from Ears and Draining Lymph Nodes of Mice Infected with Leishmania amazonensis

Authors: Emilie Giraud and Evie Melanitou, date: 06/05/2020, view: 1766, Q&A: 0

[Abstract] Parasites of the genus Leishmania infect the mammalian hosts, including mice and humans and cause cutaneous or visceral leishmaniasis depending upon the parasite species transmitted by the vector sandfly. Leishmania amazonensis is one of the Leishmania species responsible for the cutaneous form of the disease. We have ...

Evaluation of B Cell Proliferation in vivo by EdU Incorporation Assay

Authors: Adi Biram and Ziv Shulman, date: 05/05/2020, view: 2095, Q&A: 0

[Abstract] Generation of antibodies is crucial for establishing enduring protection from invading pathogens, as well as for maintaining homeostasis with commensal bacteria at mucosal surfaces. Chronic exposure to microbiota- and dietary- derived antigens results in continuous production of antibody producing cells within the Peyer’s patch germinal center ...

Environmental Conditioning and Aerosol Infection of Mice

Authors: Eriko Kudo and Akiko Iwasaki, date: 04/20/2020, view: 1893, Q&A: 0

[Abstract] Influenza infection models in mice are widely used to study flu-mediated immune responses and pathology. However, most laboratory mice are housed at 20 °C and 50% relative humidity (RH). To better recapitulate influenza epidemics and immune responses during winter seasons, mice were housed at 20 °C under different humidity conditions, 10-20% or ...

A Triple-challenge Mouse Model of Allergic Airway Disease, Primary Influenza Infection, and Secondary Bacterial Infection

Authors: Sean Roberts, Clare M Williams, Sreeja Roy and Yoichi Furuya, date: 04/20/2020, view: 1391, Q&A: 0

[Abstract] Asthma is a global problem that affects millions of individuals. An increased risk of respiratory viral and bacterial infections is one of the complications of asthma. We recently reported that mice with ovalbumin-induced allergic airway disease (AAD) are protected against influenza-Streptococcus pneumoniae co-infection. Here, we describe ...

Method for Measuring Mucociliary Clearance and Cilia-generated Flow in Mice by ex vivo Imaging

Authors: Eric Song and Akiko Iwasaki, date: 03/20/2020, view: 1703, Q&A: 0

[Abstract] Ex vivo biophysical measurements provide valuable insights into understanding both physiological and pathogenic processes. One critical physiological mechanism that is regulated by these biophysical properties is cilia-generated flow that mediates mucociliary clearance, which is known to provide protection against foreign particles and ...
