Sparse genetically defined neurons refine the canonical role of periaqueductal gray columnar organization.
La-Vu MQ, Sethi E, Maesta-Pereira S, Schuette PJ, Tobias BC, Reis FMCV, Wang W, Torossian A, Bishop A, Leonard SJ, Lin L, Cahill CM, Adhikari A. La-Vu MQ, et al. Among authors: bishop a. Elife. 2022 Jun 8;11:e77115. doi: 10.7554/eLife.77115. Elife. 2022. PMID: 35674316 Free PMC article.
These results suggest CCK cells drive threat avoidance states, which are epochs during which mice increase distance from threat and perform evasive escape. Conversely, l/vlPAG pan-neuronal activation promoted freezing, and these cells were activated near threat. ...

NO signaling in the CNS: from the physiological to the pathological.
Bishop A, Anderson JE. Bishop A, et al. Toxicology. 2005 Mar 15;208(2):193-205. doi: 10.1016/j.tox.2004.11.034. Toxicology. 2005. PMID: 15691584 Review.
Understanding the mechanisms by which NO is salutary in one set of circumstances and toxic in another is critical and will offer therapeutic targets for the mitigation of NO-mediated damage seen during CNS disease and injury. In fact, we have utilized the duality the NO to, in mo …

Differential sensitivity of oligodendrocytes and motor neurons to reactive nitrogen species: implications for multiple sclerosis.
Bishop A, Hobbs KG, Eguchi A, Jeffrey S, Smallwood L, Pennie C, Anderson J, Estévez AG. Bishop A, et al. J Neurochem. 2009 Apr;109(1):93-104. doi: 10.1111/j.1471-4159.2009.05891.x. Epub 2009 Jan 19. J Neurochem. 2009. PMID: 19226373 Free PMC article.
Here, using the high flux NO donor, spermine-NONOate, we report that oligodendrocytes are resistant to NO, while motor neurons are NO sensitive. Motor neuron sensitivity correlates with the NO-dependent formation of 3NY, which is significantly more pronounced in mot …

A key role for heme oxygenase-1 in nitric oxide resistance in murine motor neurons and glia.
Bishop A, Yet SF, Lee ME, Perrella MA, Demple B. Bishop A, et al. Biochem Biophys Res Commun. 2004 Dec 3;325(1):3-9. doi: 10.1016/j.bbrc.2004.10.010. Biochem Biophys Res Commun. 2004. PMID: 15522193
To address this question, we conducted a genetic study of the HO1 role. We show here that primary cultures of spinal motor neurons and glia from homozygous HO1-null mice are strikingly more sensitive to NO cytotoxicity than are cells expressing HO1. ...These results confir …

Mitigation of peroxynitrite-mediated nitric oxide (NO) toxicity as a mechanism of induced adaptive NO resistance in the CNS.
Bishop A, Gooch R, Eguchi A, Jeffrey S, Smallwood L, Anderson J, Estevez AG. Bishop A, et al. J Neurochem. 2009 Apr;109(1):74-84. doi: 10.1111/j.1471-4159.2009.05884.x. Epub 2009 Jan 13. J Neurochem. 2009. PMID: 19183270 Free PMC article.
IAR is dependent on the heme-metabolizing enzyme, heme oxygenase-1 (HO1), as indicated by the elimination of IAR by a specific HO1 inhibitor, and by the finding that neurons isolated from HO1 null mice have increased NO sensitivity with concomitant increased 3NY formation. …
