The medicinal uses of saffron, the dried stigmas of Crocus sativus L., have very long history in food coloring agent, and flavoring agent as well as traditional medicine for the treatment of several diseases. Crocus sativus is rich in carotenoids that affect immunity. This review summarizes the putative immunoregulatory effects of saffron and its active its derivatives including crocin, croceti...

Nutrition and immunity are the hot topics in animal’s production, and the effects of methionine on the immunity are already confirmed as the deep research on the nutrition of amino acid and immune function. However, the relationship of the methionine and immunity has not been elucidated clearly, this review aims to clarify the effects of methionine on immune function in the aspects of growth an...

Specific targets of cellular immunity in human premalignancy are largely unknown. Monoclonal gammopathy of undetermined significance (MGUS) represents a precursor lesion to myeloma (MM). We show that antigenic targets of spontaneous immunity in MGUS differ from MM. MGUS patients frequently mount a humoral and cellular immune response against SOX2, a gene critical for self-renewal in embryonal s...

Administration of Cytoxan in doses capable of inhibiting both humoral and cellular immunity markedly potentiated primary systemic vaccinia virus infection in mice. Immunosuppressed mice did not form neutralizing antibody to vaccinia virus and had a prolonged and more severe viremia than nonimmunosuppressed control mice. Passive transfer of physiologic amounts of neutralizing antibody late in th...

Temperature-sensitive mutant vaccines protect rats against Mycoplasma pulmonis infection. The role of the humoral or cellular immune response in resistance to mycoplasma infection was investigated by adoptive-transfer experiments. Spleen cells from Lewis rats vaccinated but not challenged with wild-type organisms (vaccinated) and spleen cells from rats vaccinated (or not) and challenged were ef...

The aim of our work was to study the characteristics immune status based on analysis cellular, humoral links immunity and dynamics immunoglobulins in adults with community-acquired pneumonia (CAP), their importance pathogenesis prognosis disease.

objective(s):recent evidence have proposed that tretinoin produced in the gut preferentially promote differentiation of foxp3+treg cells but inhibits th17 lymphocytes, and this may be the main immunomdulatory mechanism of tretinoin  in vivo. this study was done to investigate the effects of tretinoin in outbred white mice after challenge with sheep red blood cells (srbc). materials and methods:...

experimental autoimmune vitiligo was induced by the intradermal injection of the purified mushroom tyrosinase emulsified in complete freund’s adjuvant (cfa) in female c57bl/6 mice. the onset of vitiligo was characterized by hair hypopigmentation and total melanocyte depletion in the basal layer of the epidermis. oral administration of semipurified mushroom tyrosinase prevented experimental auto...

Innate immunity represents the first line of defence against pathogens and plays key roles in activation and orientation of the adaptive immune response. The innate immune system comprises both a cellular and a humoral arm. Components of the humoral arm include soluble pattern recognition molecules (PRMs) that recognise pathogen-associated molecular patterns (PAMPs) and initiate the immune resp...

The realization that tumor cells utilize multiple mechanisms to escape from immune recognition and destruction has stimulated interest in developing and applying immunotherapeutic strategies which target both humoral and cellular immunity to malignant cells. As a result, the tumor-associated antigens (TAA) used as targets have to be expressed on the cell surface membrane of malignant cells. Fur...
