Sleep is required to consolidate odor memory and remodel olfactory synapses.
Chandra R, Farah F, Muñoz-Lobato F, Bokka A, Benedetti KL, Brueggemann C, Saifuddin MFA, Miller JM, Li J, Chang E, Varshney A, Jimenez V, Baradwaj A, Nassif C, Alladin S, Andersen K, Garcia AJ, Bi V, Nordquist SK, Dunn RL, Garcia V, Tokalenko K, Soohoo E, Briseno F, Kaur S, Harris M, Guillen H, Byrd D, Fung B, Bykov AE, Odisho E, Tsujimoto B, Tran A, Duong A, Daigle KC, Paisner R, Zuazo CE, Lin C, Asundi A, Churgin MA, Fang-Yen C, Bremer M, Kato S, VanHoven MK, L'Étoile ND. Chandra R, et al. Among authors: l etoile nd. Cell. 2023 Jun 22;186(13):2911-2928.e20. doi: 10.1016/j.cell.2023.05.006. Epub 2023 Jun 2. Cell. 2023. PMID: 37269832 Free PMC article.
We show that spaced odor-training and post-training sleep induce long-term memory. Memory consolidation, but not acquisition, requires a pair of interneurons, the AIYs, which play a role in odor-seeking behavior. ...

Contribution of the cyclic nucleotide gated channel subunit, CNG-3, to olfactory plasticity in Caenorhabditis elegans.
O'Halloran DM, Altshuler-Keylin S, Zhang XD, He C, Morales-Phan C, Yu Y, Kaye JA, Brueggemann C, Chen TY, L'Etoile ND. O'Halloran DM, et al. Among authors: l etoile nd. Sci Rep. 2017 Mar 13;7(1):169. doi: 10.1038/s41598-017-00126-7. Sci Rep. 2017. PMID: 28279024 Free PMC article.
Prolonged exposure to an AWC sensed odor in the absence of food leads to reversible decreases in the animal's attraction to that odor. This adaptation exhibits two stages referred to as short-term and long-term adaptation. Previously, the protein kinase G (PKG), EGL …

Therapeutic plasma apheresis as a treatment for 35 severely ill children and adolescents with pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections.
Latimer ME, L'Etoile N, Seidlitz J, Swedo SE. Latimer ME, et al. Among authors: l etoile n. J Child Adolesc Psychopharmacol. 2015 Feb;25(1):70-5. doi: 10.1089/cap.2014.0080. Epub 2015 Feb 6. J Child Adolesc Psychopharmacol. 2015. PMID: 25658452 Free PMC article.
The TPA procedures were performed at Georgetown University Hospital using a protocol that processes a total of 4.5 blood volumes over 3-5 days (three treatments of 1.5 volumes each). Overall symptom improvements at 6 months post-TPA and long-term follow-up were estimated b …

A molecular readout of long-term olfactory adaptation in C. elegans.
He C, Lee JI, L'etoile N, O'Halloran D. He C, et al. Among authors: l etoile n. J Vis Exp. 2012 Dec 22;(70):4443. doi: 10.3791/4443. J Vis Exp. 2012. PMID: 23287821 Free PMC article.
These two phases of olfactory adaptation in C. elegans were described as short-term olfactory adaptation (induced after 30 min odor exposure), and long-term olfactory adaptation (induced after 60 min odor exposure). Later work from L'Etoile et al.,(4) uncovered a Pr …

Changes in cGMP levels affect the localization of EGL-4 in AWC in Caenorhabditis elegans.
O'Halloran DM, Hamilton OS, Lee JI, Gallegos M, L'Etoile ND. O'Halloran DM, et al. Among authors: l etoile nd. PLoS One. 2012;7(2):e31614. doi: 10.1371/journal.pone.0031614. Epub 2012 Feb 3. PLoS One. 2012. PMID: 22319638 Free PMC article.
Here we show that odor-induced fluctuations in cGMP levels in the adult cilia may be responsible in part for sending EGL-4 into the AWC nucleus to produce long-term adaptation. We found that reductions in cGMP that result from mutations in the genes encoding the cilia-loca …

Nuclear entry of a cGMP-dependent kinase converts transient into long-lasting olfactory adaptation.
Lee JI, O'Halloran DM, Eastham-Anderson J, Juang BT, Kaye JA, Scott Hamilton O, Lesch B, Goga A, L'Etoile ND. Lee JI, et al. Among authors: l etoile nd. Proc Natl Acad Sci U S A. 2010 Mar 30;107(13):6016-21. doi: 10.1073/pnas.1000866107. Epub 2010 Mar 10. Proc Natl Acad Sci U S A. 2010. PMID: 20220099 Free PMC article.
To navigate a complex and changing environment, an animal's sensory neurons must continually adapt to persistent cues while remaining responsive to novel stimuli. Long-term exposure to an inherently attractive odor causes Caenorhabditis elegans to ignore that odor, a proce …

Regulators of AWC-mediated olfactory plasticity in Caenorhabditis elegans.
O'Halloran DM, Altshuler-Keylin S, Lee JI, L'Etoile ND. O'Halloran DM, et al. Among authors: l etoile nd. PLoS Genet. 2009 Dec;5(12):e1000761. doi: 10.1371/journal.pgen.1000761. Epub 2009 Dec 11. PLoS Genet. 2009. PMID: 20011101 Free PMC article.
We asked which candidate members of the olfactory signal transduction pathway promote nuclear entry of EGL-4 and which molecules might induce long-term adaptation downstream of EGL-4 nuclear entry. We found that initiation of long-term adaptation, as assessed by nuc …
