Pigment mutations in the mouse which also affect lysosomal functions lead to suppressed natural killer cell activity

Scandinavian Journal of Immunology
A OrnL G Lundin


The impact of five pigment mutations in the mouse on natural killer (NK) activity was examined in inbred strains congenic for the respective mutation. Whereas the nature of pigmentation disorder was similar in the five mutant strains (beige, pallid, reduced pigmentation, pale ear, and sepia), all mutations except sepia also led to a significant change in lysosomal enzyme activities in the kidney. A significant reduction in NK activity was observed in the four strains with lysosomal impact, whereas homozygous sepia mice displayed normal NK activity. The pigment mutations analysed are located on different chromosomes and fail to cross-interact negatively with each other in the heterozygous mice. This would indicate that pigment mutations with a parallel impact on lysosomal enzyme activities probably always result in a reduction in natural killer cell activity.
