Characterization of Calcined Jade and its immunomodulatory effect on macrophage isolated from Swiss albino mice

Characterization of Calcined Jade and its immunomodulatory effect on macrophage isolated from Swiss albino mice
Calcined Jade (CJ) is a metasilicate frequently used in traditional system of medicine as tonic to vital organs with several other pharmacological activities. X-ray powder diffraction (XRPD), inductively coupled plasma mass spectrometry (ICP-MS), atomic absorption spectroscopy (AAS) and CHNS analyzer techniques were used to characterize CJ sample. CJ was administered orally to Swiss albino mice at a dose of 50, 75, 100 and 200 μg/kg body weight for 10 days and modulation of the macrophage mediated innate immune responses was studied. Flow cytometric analysis of TLR-2/4 on peritoneal macrophage revealed elevated expression of TLR-2 as compared to control. Significant increase in phagocytic activity was observed in peritoneal macrophage. The lymphoid organs weight and other toxicity parameters did not exhibit any harmful effect. To evaluate the presence of nanoparticles, CJ was dissolved in milli Q water, filtered and lyophilized. Transmission electron microscopic (TEM) analysis revealed the presence of spherical nanoparticles in CJ [14.7–142.0 nm dimension with average particle size of 64.6 nm]. In conclusion, we report stimulation of innate immune responses by CJ may partly be due to the formation of nanoparticles. Further experiments using isolated nanoparticles may further validate the role of nanoparticles.
