sulfolipid/necrosis

Virulence mechanism of infection with Mycobacterium tuberculosis is currently focused to be clarified in the context of cell surface lipid molecule. Comparing two mycobacterial glycolipids, we observed toxicity and prominent granulomatogenic activity of trehalose 6,6'-dimycolate (TDM) injection in

We previously reported that 3'-sulfoquinovosyl-1'-monoacylglycerol (SQMG) was effective in suppressing the growth of solid tumors due to hemorrhagic necrosis in vivo. In the present study, we investigated the antiangiogenic effect of SQMG. In vivo assessment of antitumor assays showed that some

This symposium was organized to provide the up-to-date knowledge on tuberculosis immunity, especially on the understanding of cytokines or Th1 cells involved in pathophysiology/protective immunity and vaccine development. Dr. Kazuo Kobayashi (Osaka City Univ.) reported their findings on the immune

The lipids located in the outer layer of Mycobacterium tuberculosis, which include sulfolipid, phthiocerol dimycocerosate (PDIM), diacyltrehalose, and polyacyltrehalose, may play a role in host-pathogen interactions. These lipids were purified using thin-layer chromatography, and their ability to

The most characteristic pathological change in mycobacterial infection is caseous necrosis followed by tuberculous cavity formation due to the cellular immunity induced by antigenic proteins and adjuvant active cell wall components. Mycobacterial cell well contains unique hydrophobic compounds
