تلاش های بیشماری جهت تهیه واکسن موثر علیه بیماری سل گاوی انجام شده است که در این راستا ایمن سازی با پلاسمید نوترکیب حاوی آنتی ژن های هدف، راهکاری امید بخش به شمار می آید. این مطالعه با هدف کلونینگ، تایید بیان و ارزیابی ایمنی زایی پلاسمیدهای یوکاریوتی کد کننده ایمونوژن های هدف در مدل موش balb/c مورد بررسی قرار گرفت. آنتی ژن های 6 esat-و cfp-10 در پلاسمید بیانی یوکاریوتی pcdna3.1(+) کلون شدند. صح...
In vitro mimicking conditions are thought to reflect the environment experienced by Mycobacterium tuberculosis inside the host granuloma. The majority of in vitro dormancy experimental models use laboratory-adapted strains H37Rv or Erdman instead of prevalent clinical strains involved during disease outbreaks. Thus, we included the most prevalent clinical strains (S7 and S10) of M. tuberculosis...
Mycobacterium microti, the vole bacillus, which was used as a live vaccine against tuberculosis until the 1970s, confers the same protection in humans as does Mycobacterium bovis bacille Calmette-Guerin (BCG). However, because the efficacy of the BCG vaccine varies considerably, we have tried to develop a better vaccine by reintroducing into M. microti the complete region of difference 1 (RD1),...
Improved vaccines capable of promoting long-term cellular immunity are urgently required for a number of diseases that remain global health problems. In the present study, we demonstrate that a tuberculosis subunit vaccine, Ag85B-ESAT-6/CAF01 (where ESAT-6 is early secreted antigenic target of 6 kDa and CAF01 is cationic adjuvant formulation 01), induces very robust memory CD4 T cell responses ...
T-cell based IFN-γ release assays do not permit distinction of active tuberculosis (TB) from successfully treated disease or latent M. tuberculosis infection. We postulated that IFN-γ and IL-2 cytokine profiles of antigen-specific T cells measured by flow-cytometry ex vivo might correlate with TB disease activity in vivo. Tuberculin (PPD), ESAT-6 and CFP-10 were used as stimuli to determine ant...
Increasing knowledge about DosR regulon-encoded proteins has led us to produce novel Mycobacterium tuberculosis antigens for immunogenicity testing in human populations in three countries in Africa to which tuberculosis (TB) is endemic. A total of 131 tuberculin skin test-positive and/or ESAT-6/CFP10-positive, human immunodeficiency virus-negative adult household contacts of active pulmonary TB...
