partially purified antigenic fractions of leishmania major promastigotes were obtained by sodium dodecyl sulfate (sds-page) and electro-elution. three isolated protein fractions designated as frac tions (fr.) 1, 2, and 3 correspond to 40-60, 60-80, 80-100 kilodalton (kda) respectively. they were used for immunization of balb/c mice against leishmaniasis. the effects of these fractions on immune...

partially fed (4 -5 days) h .a. anatolicum (iranian isolate) female adult ticks were used for preparation of antigens of midgut which are, the gut supernate antigen (gs), gut membrane antigen (gm), triton extracted gut membrane antigen ( tx-gm ) and sodium dodecyl sulphate treated triton extracted gut membrane antigen (sds-tx-gm). the new zealand white rabbits were immunized with gs, gm, tx- gm...

The synthetic disaccharide 3-O-alpha-tyvelopyranosyl-alpha-D-mannopyranoside, identical to the O antigen 9 determinant in Salmonella, covalently linked to bovine serum albumin and suspended in Freund complete adjuvant, was used as an immunogen in mice. Antibodies in high titer were formed against the O9 determinant as estimated by a bactericidal assay, whereas only low titers of hemagglutinatin...

A 68-kilodalton (kd) outer membrane protein antigen of Bordetella bronchiseptica has been identified by using monoclonal antibodies that recognized two nonoverlapping determinants. Antibody BB05 also reacted with homologous proteins from Bordetella pertussis and Bordetella parapertussis but not with another 12 organisms from various bacterial genera. Passive injection of BB05 antibody protected...

C-ASWS-M, the alkali-soluble, water-soluble cell wall antigen of Coccidioides immitis mycelia, was evaluated for its vaccine potential in mice. Vaccination with 0.5-, 1.5-, or 3-mg doses of C-ASWS-M in complete Freund adjuvant provided a significant level of protection against intraperitoneal challenge with 1,500 arthroconidia (P < 0.0001 with each dose). Vaccination with 1 mg of C-ASWS-M prote...

Methods An inflammatory pain rat model, produced by a complete Freund adjuvant (CFA) injection into the hind paw of each rat, was combined with a conditioned place avoidance (CPA) test. On day one, time spent by the rats in each of two distinct compartments during a 10min period was recorded. On day two, each rat explored one of the conditioning compartments for 30 min. Two hours after the CFA ...

To evaluate the thermo-responsive poly(N-isopropylacrylamide) (PNiPAAm) polymer as an adjuvant, we synthesized PNiPAAm through free radical polymerization and characterized it both in vitro and in vivo. The polymer when mixed with collagen type II (CII) induced antigen-specific autoimmunity and arthritis. Mice immunized with PNiPAAm-CII developed significant levels of CII-specific IgG response ...

background: it has been reported that vitamin d has broad anti-inflammatory and immunomodulatory effects. objective: to evaluate the effects of vitamin d on the expression of il-27 and il-33 in a model of experimental autoimmune encephalomyelitis (eae). methods: eae was induced in c57bl/6 mice by immunization with myelin oligodendroglial glycoprotein mixed with complete freund&apos;s adjuvant. ...
