Rhamnose and sTn antigen were co-conjugated to bovine serum albumin (BSA) for cancer vaccine development. The immune responses against sTn have been significantly augmented with the involvement of Rha-specific antibodies to enhance antigen uptake.

Antigen Antibody

The immune elimination of soluble BSA, following an intravenous injection, is accompanied by the appearance of circulating antigen-antibody complexes. The pattern of the appearance of circulating antigen-antibody complexes and the immune elimination of antigen probably depends on the amount of antigen injected, the rate of antibody synthesis, and perhaps, the quality of antibody produced. There is no relationship between the I* antigen-antibody complexes detected during the immune response in rabbits by ammonium sulfate precipitation and the material precipitated from immune sera as a result of treatment with alkali. Alkali-precipitable material present in the serum of rabbits at a time when I* antigen is also present contain at most only traces of the antigen.

Cellular Events

Cell suspensions from the spleens of normal mice or mice injected with sheep erythrocytes were separated on a discontinous bovine serum albumin density gradient. Four bands or subpopulations were obtained and were assayed for antibody-forming cells, and for antigen-sensitive precursor cells. The antibody-forming cells were assayed by the hemolytic plaque assay and the antigen-sensitive precursors were assayed by the number of plaque-forming cells which developed after 3 or 5 day's culture with antigen. It was found that both antibody-forming cells and their precursors were present in the denser region of the gradient when spleen cell suspensions were taken from unimmunized mice. In contrast, both antibody-forming cells and precursors floated to the top in cell suspensions from mice sacrificed 1, 2, or 3 days after antigen injection. The change in density was detectable as early as 12 hr and was complete by 18 hr. The cell which changed in density was specific for the antigen that brought about that change. The significance of these findings is discussed.

The mechanism of food allergy may vary. This study aimed to compare the effects of milk, yogurt, or beef meat supplementation on humoral and cellular immune responses in a mice model. Mice were divided into four groups: The “Milk group” was sensitized with a β-lactoglobulin (β-lg)/α-casein (α-CN) mixture and supplemented cow milk; the “Yogurt group” was sensitized with β-lg/α-CN and supplemented yogurt; the “Beef group” was immunized with bovine serum albumin (BSA) and supplemented beef meat; and the “PBS group” received PBS in all procedures. ELISA was used to measure humoral response, including: Total IgE, specific IgG, and IgA. Cellular response was determined by phenotyping lymphocyte from lymphoid tissue and measuring the Th1/Th2 cytokine concentration with flow cytometry. The qPCR method was used for quantification of the fecal microbiota. The results obtained revealed a lower IgE level for the Yogurt group than for the Milk one. In the Yogurt group, the contribution of regulatory T cells to MLN and PP was higher compared to the other groups. We confirmed that diet supplementation with yogurt modulates the immune response to the prime allergen, and changes the activity of serum antibodies to milk proteins and BSA. Based on a specific antibodies level, we cannot exclude the possibility of CMA mice reaction against BSA.

Genetic nonresponder guinea pigs incapable of an immune response to DNP-PLL alone were immunized with DNP-PLL complexed to ovalbumin or bovine serum albumin. Under these circumstances the animals produce both anti-DNP-PLL antibodies and antibodies directed against the conveyor albumin. Thus immune response to DNP-PLL complexed to conveyor albumin molecules can serve as a simple model of hapten-carrier relationships. To explore these relationships the question whether these two types of antibody are synthesized by the same or by different plasma cells was investigated by a combination of a double immunofluorescent technique and radioautographic localization of radioactive antigen. It was shown that the anti-DNP-PLL antibodies and the antibodies against the carrier albumin molecule were produced in separate cells. No cell-producing antibodies with both specificities were detected out of 526 cells studied.
