Previously, we have demonstrated that an anti-PA immune response comparable with that in mice subcutaneously immunized with PA protein adjuvanted with aluminium hydroxide was induced in both the systemic compartment and the mucosal secretions of the nose and lung of anaesthetized mice when they were nasally immunized with PA protein incorporated into previously reported LPD (Liposome\u2014Protamine\u2014DNA) particles. In this study, we evaluated the anti-PA immune response induced by the nasal PA\/LPD particles in non-anaesthetized mice and compared it with that in anaesthetized mice. Our data showed that the anti-PA antibody response and the anthrax lethal toxin-neutralization activity induced by the nasal PA\/LPD in non-anaesthetized mice was relatively weaker than that in anaesthetized mice. However, the splenocytes isolated from the nasally immunized mice, anaesthetized and non-anaesthetized, proliferated comparably after in-vitro re-stimulation. By evaluating the uptake of fluorescence-labelled LPD particles by phagocytes in the nasal and broncho-alveolar lavages of mice after the nasal administration, we concluded that the relatively weaker anti-PA immune response in the non-anaesthetized mice might be partially attributed to the reduced retention of the PA\/LPD particles in the nasal cavity of the non-anaesthetized mice. Data collected in this study are expected to be useful for future anthrax nasal vaccine studies when mice are used as a model.<\/jats:p>","DOI":"10.1211\/jpp.58.4.0003","type":"journal-article","created":{"date-parts":[[2006,3,20]],"date-time":"2006-03-20T21:28:24Z","timestamp":1142890104000},"page":"439-447","source":"Crossref","is-referenced-by-count":11,"title":["Evaluation of the immune response induced by a nasal anthrax vaccine based on the protective antigen protein in anaesthetized and non-anaesthetized mice"],"prefix":"10.1093","volume":"58","author":[{"given":"Brian R","family":"Sloat","sequence":"first","affiliation":[{"name":"Department of Pharmaceutical Sciences, College of Pharmacy, Oregon State University , Corvallis, OR 97331,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhengrong","family":"Cui","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical Sciences, College of Pharmacy, Oregon State University , Corvallis, OR 97331,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2006,4,1]]},"reference":[{"key":"2024103109335989300_cit1","doi-asserted-by":"crossref","first-page":"384","DOI":"10.1016\/S0014-5793(02)03609-8","article-title":"Anthrax toxin: a tripartite lethal combination","volume":"531","author":"Ascenzi","year":"2002","journal-title":"FEBS Lett."},{"key":"2024103109335989300_cit2","doi-asserted-by":"crossref","first-page":"5636","DOI":"10.4049\/jimmunol.170.11.5636","article-title":"Effective mucosal immunity to anthrax: neutralizing antibodies and Th cell responses following nasal immunization with protective antigen","volume":"170","author":"Boyaka","year":"2003","journal-title":"J.
