Figure Lengend Snippet: Humanized hu/mTNFR1-k/i mouse models. Schematic representation of the homologous recombination in the TNFR1 gene locus. Shown is the wild-type genomic locus (A), the targeted locus, including the neo cassette (B), and the genomic locus of chimeric mice (Cre’d locus; C).

Figure Lengend Snippet: Expression of transgenic hu/mTNFR1-k/i and hu/mTNFR2-k/i in homozygous mice. Splenocytes or thymocytes were isolated from C57BL/6J wild-type (A and B), hu/mTNFR1-k/i (A), or hu/mTNFR2-k/i (B) mice. Then mouse TNFR1 (HP8002) and human TNFR1 (HP9002) (A) or mouse TNFR2 (HP8003) and human TNFR2 (HP9003) (B) expression was analyzed by flow cytometry using subgates for CD45R+ B cells, CD68+ macrophages (splenocytes), and CD8+ thymocytes. Gray histograms show the isotype controls; black lines indicate signals measured for TNFR1 or TNFR2 expression. Data are presented as normalized to unit area.

Figure Lengend Snippet: Expression of transgenic hu/mTNFR1-k/i and hu/mTNFR2-k/i in primary cells isolated from homozygous mice. Primary MEFs were isolated from wild-type (A and B), hu/mTNFR1-k/i (A), or hu/mTNFR2-k/i (B) C57BL/6 mice. Expression of mouse TNFR1 (HP8002) and human TNFR1 (HP9002) (A) or mouse TNFR2 (HP8003) and human TNFR2 (HP9003) (B) was analyzed by flow cytometry. Data are presented as normalized to unit area. (C and D) Brain tissue isolated from wild-type (C and D), hu/mTNFR1-k/I (C), or hu/mTNFR2-k/i (D) C57BL/6 mice. Tissue was lyzed and expression of huTNFR1 (wild-type, hu/mTNFR1-k/i, H398) or huTNFR2 (wild-type, hu/mTNFR2-k/i, MR2-1) was analyzed by Western blot.

Figure Lengend Snippet: Mechanism of TNFR1 antagonist ATROSAB and TNFR2 agonist EHD2–scTNFR2-mediated neuroprotection. (A) TNFR1 signaling induces neurodegeneration and inflammation, whereas TNFR2 signaling promotes neuroprotection. (B) ATROSAB, an antagonistic TNFR1-selective antibody, can block TNFR1 signaling, leading to prevention of neurodegeneration and inflammation. More importantly, in the presence of ATROSAB, tmTNF stays free to activate neuroprotective signaling via TNFR2. Our data indicate that, by blocking TNFR1, ATROSAB shifts the endogenous tmTNF signaling toward neuroprotective TNFR2 signaling. Similarly, the TNFR2 agonist EHD2–scTNFR2 can directly activate TNFR2 and thereby induce neuroprotection.
