background: sand fly saliva helps parasite establishment and induce immune responses in vertebrate hosts. in the current study, we investigated the modulation of phlebotomus papatasi salivary gland antigen expression by seasonal and biological factors. methods: sand flies were grouped according to physiological stages such as unfed, fed, semi-gravid, gravid, parous, nulliparous, infected or no...
background: occurrence of resistance against antibioticsand inadequate efficacy of some vaccines necessitates studies ofnatural immunostimulators in aquaculture. shrimps shell derivedfrom chitosan can be used as immune stimulators in fish.objectives: in this study, the effects of oral administration ofchitosan, derived from shrimp shell, on some immune responsesand disease resistance in cyprinu...
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...
The vertebrate immune system is a wonder of modern evolution. Occasionally, however, correlations within the immune system lead to inappropriate recruitment of preexisting T cells against novel viral diseases. We present a random energy theory for the correlations in the naive and memory T cell immune responses. The non-linear susceptibility of the random energy model to structural changes capt...
There are numerous studies on the immune response against malignant human tumors. This study was aimed to address the complexity and specificity of humoral immune response against a benign human tumor. We assembled a panel of 62 meningioma-expressed antigens that show reactivity with serum antibodies of meningioma patients, including 41 previously uncharacterized antigens by screening of a feta...
Introduction: The exact cause of most autoimmune diseases is still unknown; however, several factors play a role in causing or exacerbating autoimmune reactions. In addition to environmental factors such as bacterial, parasitic, fungal and viral infections, factors such as genetic characteristics and lifestyle are also included. Infections caused by viruses usually trigger a strong immune respo...
Most microbial infections are either restricted to the mucosal membranes or the etiologic agents needed to transit the mucosa. Thus, it is desirable to stimulate a mucosal response following vaccination, to block both infection and disease development. Attenuated vaccine carriers mimic natural infections, triggering also mucosal responses. Similar results can be achieved by administering antige...
BACKGROUND The complexity and diversity of the antibody immune response to the antigen repertoire of a pathogen has long been appreciated. Although it has been recognized that the detection of antibodies against multiple antigens dramatically improves the clinical sensitivity and specificity of diagnostic assays, the prognostic value of serum reactivity profiles against multiple microbial antig...
