Dr. Tatiana I. Samoylova received her MS degree in Botany and Zoology from Kiev National University (Kiev, USSR) in 1982 and her PhD in Biochemistry from the Institute of Experimental Botany (Minsk, USSR) in 1991. She was a postdoctoral research associate at the Department of Molecular Genetics (IPK, Institute of Plant Genetics and Crop Plant Research, Gatersleben, Germany) from 1994 to 1996. She moved to the United States to join the Scott-Ritchey Research Center (SRRC) at the Auburn University College of Veterinary Medicine (AUCVM) as a Postdoctoral Fellow. Dr. Samoylova currently holds joint appointments as a Research Professor at the SRRC and at the Department of Pathobiology, Auburn University, College of Veterinary Medicine.
Dr. Samoylova is a protein/peptide biochemist with multiyear experience in phage display technology. Phage display is a powerful technique for identifying peptides or proteins that specifically recognize and bind to particular molecular targets. For more than 15 years, she has been applying phage display as a discovery tool for development of highly specific peptide-based diagnostic and therapeutic agents for numerous applications in human and veterinary medicine including cell targeting in genetic diseases, cancer and immunocontraception. Over the years, development of contraceptive vaccines for control of wild and feral animal populations has become Dr. Samoylova’s primary research interest and is currently the major focus of her laboratory.
Immunocontraception is a promising strategy for animal population control. Similar to anti-disease vaccination, contraceptive vaccines stimulate the animal’s own immune system to produce antibodies which interfere with one or more events in fertilization. The focus of Dr. Samoylova’s laboratory is on development of contraceptive vaccines for wild and feral animals, including cats, dogs, and pigs, using phage as a vector for immunogenic peptides. Such contraceptive vaccines are composed of whole phage particles carrying immunogenic peptides, where the phage body plays the role of a carrier protein/adjuvant and multiple peptide copies stimulate production by the animal of anti-peptide antibodies. These antibodies interfere with male and female reproductive functions, leading to reduction in fertility. Examples of antigens used in Dr. Samoylova’s laboratory for vaccine construction include zona pellucida-binding peptides as well as molecules derived from reproductive hormones and their receptors.
One of Dr. Samoylova’s projects is directed towards development of a novel type contraceptive vaccine for feral cats and stray dogs to be used as an alternative to surgical castration. A single dose, non-surgical sterilant that could be administered in the field at a reasonable cost would be an ideal solution, and would save lives and end suffering for millions of companion animals throughout the world. The goal is to create a vaccine that will fulfill these requirements. The vaccine is designed to include phage particles carrying multiple copies of gonadotropin releasing hormone (GnRH) peptides. Animals respond to such vaccines by producing anti-GnRH antibodies, which are known to affect fertility, reducing or preventing pregnancies. The project is funded by the Found Animals Foundation through Michelson Grants in Reproductive Biology. Other uses of such GnRH-based vaccines may be in the treatment of human and animal hormone-dependent reproductive cancers.
Development of contraceptive vaccines for wild pigs is another major area of Dr. Samoylova’s research. Populations of wild pigs are rapidly expanding throughout the United States, causing annual losses of up to several billion dollars in damages to agriculture and other areas of the economy. Current control programs that focus on wild pig eradication through trapping and hunting are expensive, inefficient, and unacceptable for much of the public. Unlike any other contraceptive for wildlife, Dr. Samoylova’s approach allows development of vaccines that are species-specific. Species specificity is one of the major requirements for an ideal contraceptive for wildlife since such vaccines need to be distributed in uncontrolled environments where they could contact non-target species, resulting in unwanted loss of fertility in the non-target animals. The approach is unique and protected by two issued U.S. Patents. Potentially, it can be applied to population control of multiple wildlife species. This project is a part of a larger initiative by Auburn University that includes researchers from the College of Veterinary Medicine as well as School of Forestry and Wildlife.
