Are licensed canine parvovirus (CPV2 and CPV2b) vaccines able to elicit protection against CPV2c subtype in puppies?: A systematic review of controll…
2015
Severe gastroenteritis caused by canine parvovirus type 2 (CPV2) is a serious life-threatening disease in puppies less than 4-months of age. The emergence of new variants has provoked some concern about the cross-protection elicited by licensed canine parvovirus modified-live type 2 (CPV2) and type 2b (CPV2b) vaccines against the most recent subtype CPV2c. A systematic review was carried out to assess the efficacy of commercial vaccines. We conducted a literature search of Pub Med/MEDLINE from January 1990 to May 2014. This was supplemented by hand-searching of related citations and searches in Google/Google Scholar. Controlled clinical trials in which vaccinated puppies were challenged wit…
Mechanisms of cell death in canine parvovirus-infected cells provide intuitive insights to developing nanotools for medicine
2010
Jonna Nykky, Jenni E Tuusa, Sanna Kirjavainen, Matti Vuento, Leona GilbertNanoscience Center and Department of Biological and Environmental Science, University of Jyväskylä, FinlandAbstract: Viruses have great potential as nanotools in medicine for gene transfer, targeted gene delivery, and oncolytic cancer virotherapy. Here we have studied cell death mechanisms of canine parvovirus (CPV) to increase the knowledge on the CPV life cycle in order to facilitate the development of better parvovirus vectors. Morphological studies of CPV-infected Norden laboratory feline kidney (NLFK) cells and canine fibroma cells (A72) displayed characteristic apoptotic events. Apoptosis was f…
From endosomes onwards : membranes, lysosomes and viral capsid interactions
2009
Kirsi Pakkanen haki väitöstutkimuksessaan monitieteellisen lähestymistavan avulla uusia näkökulmia virustutkimukseen. Tutkimus tuo uutta tietoa lipidikalvojen merkityksestä viruksen ja viruksen isäntäsolun elämässä. Tutkimuksessa selvisi, että koiran parvovirus, jota tutkimuksessa käytettiin mallina parvoviruksille ja yleisemmin vaipattomille viruksille, tarvitsee tietynlaisia isäntäsolun lipidikalvojen ominaisuuksia voidakseen vapautua solunsisäisten endosomirakkuloiden sisältä. Erityisen tärkeää tässä vapautumisessa näytti olevan kalvojen juoksevuus sekä jäykkien alueiden hallittu järjestäytyminen kolesterolin avulla. Hyödyntämällä molekyylejä, lääkeaineita, jotka muuttavat kolesteroliavu…
