Impact of apitherapy on canine, equine, and chicken lymphocytes, in vitro.

The researchers in this study explored the effect of apitherapy, a form of alternative medicine using bee products, on the immune system responses of dogs, horses, and chickens. The study specifically examined the impact of honey, propolis, and bee venom on the proliferation and viability of these animals’ white blood cells.

Study Methodology

• The studys’ primary aim was to understand how apitherapy, specifically using products derived from western honeybees, impacts the immune systems of dogs, horses, and chickens. The primary focus was on honey, propolis, and honeybee venom.
• The researchers conducted this study in vitro – that is, in a controlled laboratory environment rather than within the living organism of the animals. This allowed the team to more closely control and observe the impacts of the bee products on the animals’ cells.
• Peripheral blood lymphocytes (PBLs) – a type of white blood cell responsible for immune responses – from the animals were cultured with the bee products. The researchers measured the proliferation (growth and multiplication) of these cells, their viability (ability to survive), the occurrence of apoptosis (programmed cell death), and changes to the cells’ morphology (structure).
• The team used Concanavalin A (Con A) and dexamethasone as controls. Con A is commonly used to stimulate cellular activity, whereas dexamethasone typically suppresses it. This context was valuable to compare how the bee products compared to these known stimulatory and suppressive substances.

Study Findings

• The effects of the honeybee products varied depending on both the specific product used and the animal species involved.
• Honey stimulated the proliferation of PBLs in all three species. However, there was also increased cytotoxicity observed, indicating a greater death rate of cells when cultured with honey.
• Propolis had a stimulating effect on the PBLs of dogs and horses, enhancing their growth and multiplication. Contrastingly, it suppressed proliferation in chicken PBLs.
• Honeybee venom was the most potent stimulant for PBLs among all three species. Especially in horses, its impact surpassed even the traditionally used stimulant, Con A. Interestingly, the venom also improved cell viability following culture.
• The initial findings were encouraging but they suggest more research needs to be done. The ultimate goal is to understand if these honeybee products can be used as immune stimulants or inhibitors in veterinary medicine.
