Phenotype Homozygous State Susceptible to Mouse cytomegalovirus (MCMV) at a dose of 1x105 PFU. Decreased dendritic cell number: conventional DCs are reduced in bone marrow and spleen. Decreased plasmacytoid dendritic cell number: both the number and percentage of pDCs are reduced in bone marrow and spleen. Decreased NK cell number: splenic NK cells are reduced in percentage and number, bone marrow NK cells are only moderately reduced. Decreased splenocyte number: spleens and lymph nodes are consistently smaller and show reduced cellularity. Small lymph nodes. Abnormal dendritic, marcophage and NK cell physiology. Decreased body weight.
