Background & Objective: DNA vaccines as a new generation of vaccines require adjuvant to improve vaccine immunogenicity; adjuvants can also increase the DNA vaccine efficacy. In this study, the effects of the host’s interferon-inducible Mx protein as bio adjuvant and conventional alum adjuvant were evaluated.   Materials & Methods: The BALB/c mice were immunized by different prime-boost strate...

background: cystic echinococcosis (ce), also known as echinococcosis/hydatidosis, is one of the most important parasitic diseases in the world. it enhances both humoral and cellular (th1 and th2) responses in infected host. different antigens of the worm may favor the th1 or th2 immune responses in ce patients. objective: to evaluate the humoral and cellular immune responses of balb/c mice agai...

<b><i>Background:</i></b> Chronicity or seroclearance of hepatitis B virus (HBV) antigens is determined by the host immune responses. Current approaches to treat HBV patients are based on inhibition replication using different antivirals (nucleoside nucleotide analogs) as monotherapy, along with modulators combination therapy being used worldwide for reducing viral load....

objective(s):gemifloxacin is a broad spectrum antibiotic and has shown excellent coverage against a wide variety of microorganisms. in this study, an attempt was made to evaluate the immunomodulatory potential of gemifloxacin in male swiss albino mice in vivo. materials and methods: three doses of gemifloxacin 25 mg/kg, 50 mg/kg and 75 mg/kg were used intraperitoneally (ip) for the evaluation o...

Aging is typically associated with a decrease in immune function. However, aging does not affect each branch of the immune system equally. Because of these varying effects of age on immune responses, aging could affect taxa differently based on how the particular taxon employs its resources towards different components of immune defense. An example of this is found in the humoral immune system....

Protein vaccines combined with adjuvants have been widely used to induce immune responses, especially the humoral immune response, against molecular targets including parasites. Follicular T helper (Tfh) cells are the specialized providers of B-cell help, however, the induction of Tfh cells in protein vaccination has been rarely studied. Here, we report that the Schistosoma japonicum recombinan...

Background: Development of an effective vaccine is highly needed in order to restrict the AIDS pandemic. DNA vaccines initiate both arms of immunity without the potential of causing disease. HIV-1 p24 and gp41 (gag and env) proteins play important roles in viral pathogenesis and are effective candidates for immune induction and vaccine design. Objective: In this study, new DNA vaccine candidate...

Objective(s): The results of studies on vaccine development for foot-and-mouth disease (FMD) virus show that the use of inactivated vaccines for FMD virus is not completely effective. Novel vaccinations based on immuno-dominant epitopes have been shown to induce immune responses. Furthermore, for safety of immunization, access to efficient adjuvants against FMD virus seems to be critical.Materi...
