Experimental models of murine glomerular disease with known DC- and Mac-related pathogeneses
| Model | Mechanism | DC/Mac function |
|---|---|---|
| Nephrotoxic nephritis (NTN)89 | Glomerular injury- induced by the injection of mouse/rat renal cortex into a heterologous species (eg sheep, rabbits), then the Abs introduced into rodents | Ag/Ab complexes endocytosed by MHC II+ DC and Ag presented to CD4+ T cells. Mac are the main effector cells201. Aggravation of damage after early depletion of CD11c+ DC92. |
| Glomerulonephritis – (NOH mice 104) | Podocyte injury - the promoter for podocyte-specific human nephrin fused to cDNA encoding the transmembrane domain of the transferrin receptor, ovalbumin (OVA), and hen egg lysozyme (HEL) | Injection of activated OT-II (OVA-specific) Th cells, intra-renal stimulation. Periglomerular infiltrate, Mac-like: CD11c+, CD86+, MHC II+, CD11bhi/int, Gr1+ |
| Lupus models: | ||
| BWF1 mice 202 | F1 hybrid strain created from mating New Zealand black and white mice205, 206 | Mononuclear cell infiltration in kidney. Attraction of autoreactive T and B cells to kidney and expansion in draining lymph node114. CD11b+CD11c+ intrarenal DC/Mac are the source of B lymphocyte chemokine106. |
| B6.TC mice203 | Mice homozygous for the NZM2410 lupus susceptibility QTL (Sle1, Sle2 and Sle3) | DC from these mice demonstrate higher CD40 expression 207 DC have higher T cell allostimulatory capacity111 |
| NZM2328 mice 204 | Derived by selective inbreeding of progeny of a cross between NZB and NZW mice | Intraglomerular CD11c+ DC, F4/80+ Mac are confined to interstitial regions |
