Phagolysosomal Trafficking Assay
Author:  Alka Mehra, date: 07/05/2014, view: 5733, Q&A: 0
Phagolysosomal trafficking is an important innate defense pathway that clears microbes by delivering them to lysosomes, the degradative compartment of the cell. Mycobacterium tuberculosis (Mtb), the causative agent of tuberculosis, subverts ...
Analysis of Mycobacterial Protein Secretion
Authors:  Alka Mehra and Jennifer A. Philips, date: 06/20/2014, view: 4812, Q&A: 0
Mycobacterium tuberculosis (Mtb) is the causative agent of tuberculosis. Analysis of proteins secreted by Mtb has been of interest to the field of tuberculosis research since certain secreted proteins interact with the host to promote ...

Confocal Imaging of Myeloid Cells in the Corneal Stroma of Live Mice
Authors:  Matilda F. Chan and Zena Werb, date: 07/05/2015, view: 3232, Q&A: 0
The accessibility and transparency of the cornea makes it a good tissue model for monitoring immunological responses using in vivo real time imaging analysis (Lee et al., 2010; Tan et al., 2013). These corneal qualities ...

Animal Models of Corneal Injury
Authors:  Matilda F. Chan and Zena Werb, date: 07/05/2015, view: 2648, Q&A: 0
The cornea is an excellent model system to use for the analysis of wound repair because of its accessibility, lack of vascularization, and simple anatomy. Corneal injuries may involve only the superficial epithelial layer or may penetrate deeper to ...

In vitro Detection of Neutrophil Traps and Post-attack Cell Wall Changes in Candida Hyphae
Authors:  Alex Hopke and Robert T. Wheeler, date: 04/05/2017, view: 1107, Q&A: 0
In this protocol we describe how to visualize neutrophil extracellular traps (NETs) and fungal cell wall changes in the context of the coculture of mouse neutrophils with fungal hyphae of Candida albicans. These protocols are easily ...

Activity-based Pull-down of Proteolytic Standard and Immunoproteasome Subunits
Activity-based probes (ABP) are small organic molecules that irreversibly bind to the active center of a specific enzyme family and may be coupled to a fluorophore or an affinity tag (Li et al., 2013). Here, we describe a method to ...
