The efficacy and safety of subcision using CO gas combined with fractional laser for acne scars: Clinical and microscopic evaluation.

Background: Various modalities have been used to treat acne scars. CO fractional laser is an effective and commonly used treatment. CO gas injection into the dermis by needle with high pressure can cause fibrotic collagen breakage, producing the effects of subcision.

CM1 ligation initiates apoptosis in a caspase 8-dependent manner in Ramos cells and in a mitochondria-controlled manner in Raji cells.

Burkitt lymphoma (BL) is a tumor with the characteristics of germinal center B cells. We previously reported that the CM1 (centrocyte/-blast marker 1) molecule is expressed only in germinal center B cells, specifically, in a subpopulation of centroblasts and centrocytes. In the present study, we investigated the apoptosis induced by anti-CM1 in the Ramos and Raji human BL cell lines.

Fas ligand mRNA expression in the mouse central nervous system.

Fas ligand (FasL) expressing cells delete Fas bearing T cells, thereby enabling privileged immune status in the brain. Although the presence of FasL immunoreactivity has been shown in various cell types in the central nervous system, the precise in vivo distribution of FasL mRNA in mammals is not known. Accordingly, we localized intense FasL mRNA signals in neuroglial cells mainly within the white matter regions.
