Summary
Veterinary immunomodulators, including bacterial products, are now available to stimulate the immune system. These nonspecific agents activate macrophages and influence lymphocyte activity for various therapeutic uses.
Area of Science:
- Veterinary immunology
- Immunotherapy
- Biological products
Background:
- Biological products for immunomodulation are licensed in veterinary medicine.
- These products activate macrophages, induce cytokines, and affect lymphocyte activity.
- Commonly used products include inactivated Propionibacterium acnes, Mycobacterium spp. cell walls, and Staphylococcus aureus lysate.
Purpose of the Study:
- To review the current state of immunomodulation in veterinary medicine.
- To discuss the mechanisms and applications of licensed veterinary biological products.
- To explore both approved and off-label uses of these immunomodulators.
Main Methods:
- Review of licensed biological products for veterinary use.
- Analysis of scientific literature on immunomodulator effects.
- Examination of mechanisms involving macrophages, cytokines, and lymphocytes.
Main Results:
- Licensed immunomodulators activate macrophages and cytokine production.
- These products impact B and T lymphocyte proliferation and activity.
- Off-label usage studies indicate broader potential applications.
Conclusions:
- Veterinary immunomodulation is feasible with licensed biological products.
- These agents act as nonspecific immune system stimulators.
- Humoral and cellular immunity can be modulated by these products.

The Tumor Microenvironment
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...
Cancer Therapies
Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Combination Therapies and Personalized Medicine
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Cytotoxic T Cells-mediated Immune Response
Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...

Tumor Immunotherapy
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
Cancer Vaccines
Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...
