[Effect of immunization with neurospecific proteins and tubulin on learning in the rat].
The paper deals with the effect of anticerebral antibodies on rats learning in T-shaped maze with food reinforcement. The rats of August line were immunized by neurospecific proteins 10-40-4 from the human and rat's brain, 14-3-2 and cerebral tubuline. Rats immunized by bovine serum albumine (BSA) served as a control of the influence of antibodies to noncerebral protein. Rats injected with Freund adjuvant and saline, served as control of Freund adjuvant action. At the time of antibodies formation (from the 7-th day after the last injection) the rats were trained in a T-shaped maze during 4 days. The acquisition of conditioned reactions was inhibited in rats immunized with neurospecific proteins 10-40-4 from the rats brain, 14-3-2 and cerebral tubuline. Antibodies to neurospecific protein 10-40-4 from the rats brain produced the greatest effect on the process of learning. They elicited a significant decrease of conditioning and an increase of the number of errors. Antibodies to the neurospecific protein 10-40-4 from the human brain and to the BSA, i.e. to proteins which are not present in the nervous tissue of the rats, did not affect the learning. The obtained results indirectly confirm the permeability for the antibodies of the blood-brain barrier in immunized animals.
