Strain: LEW.1AV1

Symbol: LEW.1AV1
Strain: LEW.1AV1
RGD ID: 737657
Citation ID: RRID:RRRC_00201
Ontology ID: RS:0000491
Also Known As: LEW.1AV1(DA)
Type: congenic
Available Source: Not Available
Origination: National Veterinary Institute, Uppsala, Sweden
Description: Originally derived by Dr. Hans J. Hedrich at Versuchstierzucht, Hannover, Germany by transgressing the MHC of DA/Han rats (AV1) into LEW/Han rats for 16 backcross generations. RT1av1 haplotype is a variant to the standard a- haplotype with the difference residing in the atypical MHC class I region.
Inbred Generations: F38
Last Known Status: Extinct

RGD Curation Notes
Note Type Note Reference
strain_drgs_chems No macroscopic symptoms were observed in rats injected with IFA emulsified with water but when arthritogenic adjuvants like pristane, mycobacteria, MDP, avridine were added arthritis incidence and severity was increased. Beta glucan solution was able to induce arthritis when injected without IFA. 737660
strain_drgs_chems Resistant to arthritis induced by injection of adjuvant oil squalene. 62404
strain_life_disease None of the LEW.1AV1 rats which were injected with IFA (incomplete Freund's adjuvant) developed arthritis whereas only 17% of (DA x LEW.1AV1)F1 , 46% of (DA x LEW.1AV1)F2 and 75% of DA x F1 developed arthritis. 61087
strain_life_disease These are susceptible to collagen-induced arthritis whereas common LEW rats are not. They develop less severe arthritis 30 days after immunization with IFA, hence the arthritis score late in disease is higher than the DA rats. 737659
strain_other The genome of PVG.1AV1 depicts more arthritis resistance than that of LEW.1AV1. 737700
