Liposome encapsulated all trans retinoic acid (ATRA) has enhanced immunomodulatory and inflammation reducing activities in mice model.

The all trans retinoic acid (ATRA) is found to have a promising regulatory effect on immune system and inflammatory responses in experimental research. The purpose of this study was to investigate whether this therapeutic efficiency of ATRA could be enhanced by encapsulating into a liposome formulation composed of Distearoyl-L-phosphatidylcholine (DSPC) and cholesterol utilizing a well-established mice model. The humoral antibody titer (HA), delayed-type hypersensitivity (DTH), bone marrow cellularity, hematology, and levels of α- esterase-positive cells, were taken as parameters to assess the level of immunomodulation in the sheep red blood cells (SRBC) immunized and challenged BALB/c mice.

Anti-metastatic study of liposome-encapsulated all trans retinoic acid (ATRA) in B16F10 melanoma cells-implanted C57BL/6 mice.

B16F10 cells-induced C57BL/6 mice were divided into several groups and the free all trans retinoic acid (ATRA) and liposome-encapsulated ATRA were given for 21 days. The encapsulated ATRA treatment lowered the oxidative stress and lipid profile near to the normal level in the drug-treated mice. Encapsulated ATRA treatment showed substantial decrease in serum cytokines and increase in lifespan when compared with free ATRA treatment.

Antioxidant potential of all-trans retinoic acid (ATRA) and enhanced activity of liposome encapsulated ATRA against inflammation and tumor-directed angiogenesis.
