Antonin Bukovsky
Blood mononuclear cells consist of T cells and monocyte derived cells. Beside immunity, the blood mononuclear cells belong to the complex tissue control system (TCS), where they exhibit morphostatic function by stimulating proliferation of tissue stem cells followed by cellular differentiation, that is stopped after attaining the proper functional stage, which differs among various tissue types. Therefore, the term immune and morphostatic system (IMS) should be implied. The TCS-mediated morphostasis also consists of vascular pericytes controlled by autonomic innervation, which is regulating the quantity of distinct tissues in vivo...

Although Kaejadan (KJD), an herbal cocktail of three medicinal plants (Lithospermum erythrorhizon, Cinnamomum loureirii, and Salvia miltiorrhiza), has been traditionally used for the treatment of rheumatoid arthritis, its scientific evidence is not fully understood. Hence, we investigated antiinflammatory and analgesic mechanism of KJD in vivo and in vitro. Kaejadan suppressed the number of writhing responses in mice treated by acetic acid and showed antinociceptive effect by tail-flick test. Kaejadan abrogated serotonin or carrageenan or Freund's complete adjuvant (FCA)-induced paw edema and also reduced the level of Evans Blue for vascular permeability...

Liver X receptors (LXRs) have been increasingly recognized as a potential therapeutic target to treat pathological conditions ranging from vascular and metabolic diseases, neurological degeneration, to cancers that are driven by lipid metabolism. Amidst intensifying efforts to discover ligands that act through LXRs to achieve the sought-after pharmacological outcomes, several lead compounds are already being tested in clinical trials for a variety of disease interventions. While more potent and selective LXR ligands continue to emerge from screening of small molecule libraries, rational design, and empirical medicinal chemistry approaches, challenges remain in minimizing undesirable effects of LXR activation on lipid metabolism...
