  • Title: Enhanced immunoprotective potential of Mycobacterium tuberculosis Ag85 complex protein based vaccine against airway Mycobacterium tuberculosis challenge following intranasal administration.
    Author: Giri PK, Verma I, Khuller GK.
    Journal: FEMS Immunol Med Microbiol; 2006 Jul; 47(2):233-41. PubMed ID: 16831210.
    Abstract:
    This study examined the role of intranasal vaccination with Mycobacterium tuberculosis antigen85 complex proteins formulated in dimethyldioctadecylammonium bromide against airway Mycobacterium tuberculosis challenge in mice. Intranasal vaccination with antigen85A and antigen85B induced a significantly higher level of interferon-gamma, interleukin-12 and interleukin-4 in cervical lymph nodes together with IgA and IgG, predominantly IgG2a isotype in nasal secretion over subcutaneous vaccination. Further, intranasal vaccination with antigen85A and antigen85B imparted protection comparable with that obtained from intranasal or subcutaneous Mycobacterium bovis bacillus Calmette-Guerin immunization. These results suggest that mucosal vaccination via the intranasal route is of importance in the development of vaccine for tuberculosis.
