Weekly neutrophil counts.

Three cohorts of age-matched wild-type mice (A) and mice heterozygous (B) and homozygous (C) for the V72M NE allele were bled weekly for 6 weeks and the number of neutrophils quantified. Each line represents a single animal. One heterozygous mouse died after week 4 (♦); one homozygous mouse developed an eye infection after week 2 (+).
