Assessment of the functions of cultured lymphocytes when exposed to drugs used in cosmetology

The aim of the study was to determine the number of lymphocytes, intracellular cytokines produced by lymphocytes, and the cell cycle of lymphocytes isolated from the blood of patients when exposed to various drugs, as well as to assess the functions of cultured lymphocytes when exposed to drugs in vivo and in vitro.

Materials and methods. The study involved lymphocytes isolated from the blood of healthy women under various conditions. At the first stage of the study, T-lymphocytes were isolated from the blood of patients before exposure to the drug. The absolute and relative lymphocyte count, the number of intracellular cytokines, and the cell cycle were determined.

At the second stage, the drugs were added to the nutrient medium, where lymphocytes isolated from the blood of patients who did not receive systemic drugs were cultured. The placental extract preparation was added to the lymphocytes isolated from the first group of patients, while the hyaluronic acid preparation was added to the lymphocytes isolated from the second group of patients.

At the third stage, the lymphocytes isolated from the blood of patients after systemic exposure to the placental extract preparation or hyaluronic acid preparation were isolated and cultured, after which the same lymphocyte parameters were determined.

Results. The number of T-lymphocytes increased with the systemic use of the placental extract and hyaluronic acid preparations and practically did not change compared with the baseline data, when these drugs were added to the nutrient medium. Placental extract and hyaluronic acid had a positive effect on the mitotic activity of cells; it is worth noting that the effect of placental extract was greater than that of hyaluronic acid. Both drugs did not have a negative effect on apoptosis of T-lymphocytes. Under the effect of placental extract, lymphocytes secreted more interleukins, which contributed to proliferation of keratinocytes.

Conclusion. The placental extract and hyaluronic acid preparations have a stimulating effect on keratinocytes. The placental extract preparation has a stimulating effect on T-lymphocytes after systemic exposure of the body to it.
