cardiovascular system
• in knockouts, LPS treatment induces glomerular and peri-tubular capillary vascular congestion as well as occasional peritubular endothelial cell karyorexis and karyolysis, compared to induction of mild congestion in wild-type
• after LPS treatment
• after LPS treatment, livers from knockouts show vascular congestion
• after LPS treatment, lungs from knockouts show vascular congestion
• after LPS treatment, spleens from knockouts show vascular congestion of the red pulp
• in response to LPS stimulation, one day later, a pronounced increased in organ/tissue specific permeability is observed in nulls compared to wild-type, particularly in the lung, liver, and kidney

hematopoietic system
• after LPS treatment, spleens from knockouts show vascular congestion of the red pulp

homeostasis/metabolism
• one day after LPS administration, lungs from knockouts show edema compared to treated wild-type lungs

immune system
• after LPS treatment, spleens from knockouts show vascular congestion of the red pulp
• after LPS treatment over a 24-hour period, cytokine levels in the serum of null mice are elevated
• sinusoidal and portal inflammation is observed in knockouts following LPS treatment

liver/biliary system
• after LPS treatment, livers from knockouts show vascular congestion
• sinusoidal and portal inflammation is observed in knockouts following LPS treatment

N normal phenotype
immune system
• larger numbers of cells from the spleen and lymph nodes of arthritic null animals migrate into the joints of arthritic mice than cells from wild-type mice
• lymph node cells taken on day 14 from immunized mice produce significantly larger amounts of IFNG in response to stimulation by denatured CII or concanavalin A; cells obtained from mice on day 28 also produce greater amounts of IFNG in response to CII, but not concanavalin A
• 6 weeks after initial CII immunization, joints of nulls showed more severe inflammation than wild-type
• mice have an earlier arthritis onset after CII immunization and a higher incidence (55.3% by day 33 versus 25.7% by day42 in wild-type) than wild-type

respiratory system
• neonatal mutant lungs show a significant reduction in wound-induced endothelial cell (EC) migration relative to wild-type lungs
• however, no significant differences in lung EC content, proliferation or survival are observed
• although appropriately inflated, mutant lungs display a very disorganized architecture at P1
• at P7, secondary septation appears to be retarded relative to wild type mice
• postnatal mutant lungs display evidence of arrested/delayed alveolarization
• by 8 weeks of age (adult), differences in alveolarization are smaller but still present
• at P1, P7 and at 8 weeks (adult), mean alveolar areas are significantly increased while radial alveolar counts are significantly reduced, indicating impaired alveolarization
• however, no significant differences in alveolar cell apoptosis are observed by TUNEL staining
• at P1, mutant primary alveolar sacs are larger than wild-type
• at P1, mutant alveolar walls are thicker than wild-type
