immune system
increased leukocyte cell number ( J:129331 )
• the number of neutrophils and lymphocytes is increased 2-fold compared to in wild-type mice
abnormal neutrophil physiology ( J:129331 )
• when stimulated with formyl-peptide, neutrophils form and retract pseudopodia at inappropriate locations around the entire perimeter of the cell, migrate slower than wild-type neutrophils, and exhibit decreased adhesion

hematopoietic system
extramedullary hematopoiesis ( J:129331 )
• in the red pulp of the spleen
increased leukocyte cell number ( J:129331 )
• the number of neutrophils and lymphocytes is increased 2-fold compared to in wild-type mice
abnormal neutrophil physiology ( J:129331 )
• when stimulated with formyl-peptide, neutrophils form and retract pseudopodia at inappropriate locations around the entire perimeter of the cell, migrate slower than wild-type neutrophils, and exhibit decreased adhesion

growth/size/body
enlarged spleen ( J:129331 )
