Název v původním jazyce

Comparison of Protective Effect of Protein and DNA Vaccines hsp90 in Murine Model of Systemic Candidiasis

Popis výsledku v původním jazyce

ABSTRACT. Preventive vaccination by a hsp90-expressing DNA vaccine and recombinant hsp90 proteinvaccine, both derived from the Candida albicans hsp90 using BALB-c mouse model of systemic candidiasis,was performed. Hsp90 mRNA was cloned from a clinical isolate of C. albicans, converted to cDNA andcloned into vaccination plasmid pVAX1. Two methods of DNA application were tested: intramuscular (i.m.)and intradermal (i.d.) injection. Recombinant protein was applied by i.d. injection with Freund's adjuvant;the control groups received PBS or Freund's adjuvant only. Mice were vaccinated and after 19 d re-vaccinated.After 3 weeks, the mice were challenged with the live C. albicans in a dose of 5 x 106 CFU per mouse.After the challenge, the mice vaccinated i.d.with DNA vaccine survived for 39 and 64 % longer comparedto those receiving Freund's adjuvant and/or PBS, respectively. The i.m. application of the DNA vaccine didnot provide any significant protectivity. The serum level of anti-candida-
