[Histonet] eosinophilic crystals in mouse lung answer

[Gayle Callis]

Dear All, 

The question has been answered by Dr. JoAnn Schuh, and much appreciated. 

She wrote:  

Eosinophilic crystals in mouse lungs are not an artefact.  The crystals 
form from an endogenous protein, YM-1, that is an autocrystallizing 
protein.  These crystals in the lung, and a related crystal-forming 
protein (YM-2) in the gastrointestinal tract are most frequent in 
certain strains of mice (C57BL/6, 129, SW, etc.) and generally are 
associated with lung or gastrointestinal injury, respectively.  FYI, I 
have attached a publication on the characterization of these crystals in 
the lungs.

Best regards,

JoAnn

She also attached a pdf of publication and if anyone is interested via
private email.
