growth/size/body
• mice are runted prior to weaning
• mice exhibit lower body weights throughout life
• mice treated with an alpha IL-1R blocking antibody show weight gain
• sick mice exhibit enlarged spleen

digestive/alimentary system
• pronounced neutrophilia is seen in the duodenums, with neutrophilic infiltration of the submucosa and lamina propria that extends into the underlying muscularis externa

hematopoietic system
• sick mice exhibit enlarged spleen
• pronounced neutrophilia is seen in the joints, duodenums, and kidney glomeruli
• increase in neutrophils in the peripheral blood of sick mice compared to healthy littermates
• increase in levels of neutrophils in spleen, and in peripheral and mesenteric lymph nodes
• mice treated with an alpha IL-1R blocking antibody show decreased levels of neutrophils in both the spleen and lymph nodes
• slight increase of T cells in the spleen, however there are no changes in T cells in the lymph nodes
• decrease in blood lymphocytes
• B cell numbers are modestly decreased in the lymph nodes
• increase in monocytes in the peripheral blood of the sick mice compared to healthy littermates
• increase in levels of monocytes in spleen, and in peripheral and mesenteric lymph nodes
• mice treated with an alpha IL-1R blocking antibody show decreased levels of monocytes in both the spleen and lymph nodes

homeostasis/metabolism
• serum levels of cytokines and chemokines (IL-1 alpha, IL-1 beta, IFN-gamma, IL-6, MCP-1) are elevated
• mice treated with an alpha IL-1R blocking antibody show decreased IL-1bbeta, MCP-1, and TNF levels, however, levels of IL-18 are unchanged
• mice develop severe limb swelling, most noticeably in the tibiotarsal (heel) joint
• tibiotarsal joint swelling is 100% penetrant, although age of onset varies, beginning as early as 4 weeks or as late as 10 weeks of age
• substantial neutrophilic infiltration with slight to severe bone and cartilage erosion is seen in the tibiotarsal joint
• mice treated with an alpha IL-1R blocking antibody show decreased tibiotarsal joint swelling

immune system
• sick mice exhibit enlarged spleen
• pronounced neutrophilia is seen in the joints, duodenums, and kidney glomeruli
• increase in neutrophils in the peripheral blood of sick mice compared to healthy littermates
• increase in levels of neutrophils in spleen, and in peripheral and mesenteric lymph nodes
• mice treated with an alpha IL-1R blocking antibody show decreased levels of neutrophils in both the spleen and lymph nodes
• slight increase of T cells in the spleen, however there are no changes in T cells in the lymph nodes
• decrease in blood lymphocytes
• B cell numbers are modestly decreased in the lymph nodes

• mice treated with an alpha IL-1R blocking antibody show decreased levels of monocytes in both the spleen and lymph nodes
• serum levels of cytokines and chemokines (IL-1 alpha, IL-1 beta, IFN-gamma, IL-6, MCP-1) are elevated
• mice treated with an alpha IL-1R blocking antibody show decreased IL-1bbeta, MCP-1, and TNF levels, however, levels of IL-18 are unchanged
• sick mice exhibit enlarged lymph nodes
• mice exhibit systemic inflammation, with nearly all tissues showing neutrophilic infiltration
• pronounced neutrophilia is seen in the duodenums, with neutrophilic infiltration of the submucosa and lamina propria that extends into the underlying muscularis externa
• substantial neutrophilic infiltration with slight to severe bone and cartilage erosion is seen in the tibiotarsal joint
• mice show varying degrees of kidney damage, with some mice having fibrin and neutrophil accumulation within the glomeruli indicating necrotizing glomerulonephritis, while others have some glomeruli with only thickened membranes

renal/urinary system
• some mice exhibit glomeruli with only thickened membranes
• mice show varying degrees of kidney damage, with some mice having fibrin and neutrophil accumulation within the glomeruli indicating necrotizing glomerulonephritis, while others have some glomeruli with only thickened membranes

skeleton
