Gicerin, an Ig-superfamily cell adhesion molecule, has homophilic adhesion activity, thus leading to the formation of gicerin aggregates. Gicerin is highly expressed in various embryonic tissues, and it contributes to development through its adhesive activities. In contrast, the expression of the protein is limited to the muscular tissues and endothelial(More)
There is worldwide concern over the possibility of a new influenza pandemic originating from the highly pathogenic avian H5N1 influenza viruses. We herein demonstrate that functional air filters impregnated with ostrich antibodies against the hemagglutinin of the H5N1 virus protect chickens from death by H5N1 transmission. These results suggest that the use(More)
Gicerin is a cell adhesion molecule in the immunoglobulin superfamily. This molecule has homophilic and heterophilic adhesive activities, binding to the neurite out-growth factor (NOF). We have previously reported that gicerin plays an important role in the development and regeneration as well as in the metastasis of tumors through its adhesive activities,(More)
The most effective method for the prevention of influenza infection would be prophylaxis with a safe and effective vaccine and anti-viral materials. After vaccination, neutralizing antibodies are generated by plasma cells following various immune responses, thus resulting in protection against an infectious agent expressing the same antigens. However, in(More)
SC1 is an immunoglobulin superfamily cell adhesion molecule purified from the Gallus gallus spinal cord. SC1 is present in embryonic tissues and plays a role in chick development through its cell adhesive property. Interestingly, increased SC1 expression is observed in some sporadic tumours of the chicken, including Marek's disease-induced lymphomas and in(More)
