growth/size/body

hematopoietic system
abnormal mast cell physiology ( J:349248 )
• high-affinity IgE receptor-mediated calcium response of bone marrow-derived mast cells following activation with antigen is increased compared to the response seen in antigen-activated wild-type mast cells, without a corresponding increase in degranulation

homeostasis/metabolism
increased ceramide level ( J:349248 )
• concentrations of sphinganine (C18:0) and sphingosine (C18:1) and total ceramide levels, as well as individual long- and very long-chain ceramide species, are increased in bone marrow-derived mast cells
increased sphingosine level ( J:349248 )
• concentration of sphingosine (C18:1) is increased in bone marrow-derived mast cells

immune system
abnormal mast cell physiology ( J:349248 )
• high-affinity IgE receptor-mediated calcium response of bone marrow-derived mast cells following activation with antigen is increased compared to the response seen in antigen-activated wild-type mast cells, without a corresponding increase in degranulation
