mortality/aging

integument
• 2-fold increase in trans-epidermal water loss
• however, outside-in epidermal barrier is normal
• mild skin defect
• reduced number of intact cornified envelopes
• however, treatment with IL18-blocking antibodies rescues number of intact cornified envelopes

immune system
• increased IL33 in the serum of newborn mice
• in newborn mice but not epidermal extracts
• increased IL33 in epidermal extracts

cardiovascular system
• increased vascularization at the dermal/epidermal interface indicated by increased PECAM staining
• leaky capillary in the lungs at P0

growth/size/body
• mild postnatally

homeostasis/metabolism
• increased IL33 in the serum of newborn mice
• in newborn mice but not epidermal extracts
• 2-fold increase in trans-epidermal water loss
• however, outside-in epidermal barrier is normal
