The host immune response to pathogen infection is a tightly regulated process. Utilizing a lipopolysaccharide lung exposure model in mice, it is possible to conduct high resolution evaluations of the complex mechanisms associated with disease pathogenesis.

Immunology and Infection

Daniel E. Rothschild¹, Tara Srinivasan², Linette A. Aponte-Santiago¹, Xiling Shen^2,3,4, Irving C. Allen¹

¹Department of Biomedical Sciences and Pathobiology, Virginia Maryland College of Veterinary Medicine, Virginia Tech, ²Department of Biomedical Engineering, Cornell University, ³School of Electrical and Computer Engineering, Cornell University, ⁴Department of Biomedical Engineering, Duke University

Here, a protocol to harvest, maintain, and treat mouse small intestinal organoids with pathogen associated molecular patterns (PAMPs) and Listeria monocytogenes is described, as well as emphasis on gene expression and proper normalization techniques for protein.

Minimal erythema dose (MED) testing is used to establish dosage schedules for ultraviolet radiation phototherapy. It can assess individual variation in inflammatory response but lacks methodology for achieving reproducible results. Here, we present a precision implementation of MED and demonstrate its ability to capture individual variation in inflammatory response.
