In an attempt to select mAbs specific for human TCR-gamma/delta, a polyclonal CD3+ 4-8-WT31- (TCR-gamma/delta+) cell line (MV1) was used for mice immunization. An mAb, termed BB3, reacted with MV1 cells but not with a large panel of CD3+ WT31+ (TCR-alpha/beta+) cell populations or clones. In addition, BB3 mAb reacted with the majority of CD3+ WT31- clones derived from six different donors. Doub...

Purpose: Bombesin and bombesin receptors have been shown to play a role in cancer. Whereas the gastrin-releasing peptide (GRP) receptor is a bombesin receptor subtype frequently expressed by tumors, the other three subtypes, the neuromedin B (NMB), BB3, and BB4 receptors, have been poorly investigated in human tissues. Experimental Design: We investigated 161 human tumors for their bombesin rec...

Two mAbs directed to the TCR-gamma/delta were analyzed for their pattern of reactivity with CD3+WT31- cell populations or clones. In normal individuals, the BB3 mAb reacted with approximately 2/3 of peripheral blood CD3+WT31- lymphocytes, whereas delta-TCS-1 stained approximately 1/3 of such cells. In addition, the sum of the percentages of BB3+ and delta-TCS-1+ cells approximated the percentag...

We examined the developmental profile of TCR-gamma/delta+ cells with respect to CD45RO expression. Although total TCR-gamma/delta+ cells were negligible in the neonatal blood and increased with advancing age, most blood TCR-gamma/delta+ cells markedly expressed CD45RO without a distinction of age, probably reflecting a different CD45RO expression of two subsets defined by BB3 and delta TCS1 mAb...

Hepatocyte growth factor (HGF), efficacious in preclinical models of acute central nervous system injury, is burdened by administration of full-length proteins. A multiinstitutional consortium investigated the efficacy of BB3, a small molecule with HGF-like activity that crosses the blood-brain barrier in rodent focal ischemic stroke using Stroke Therapy Academic Industry Roundtable (STAIR) and...

Gastroesophageal reflux disease (GERD) is a disorder that is related to an incompetent lower esophageal sphincter (LES). Previous studies showed that bombesin could increase LES pressure in humans and opossums. The aim of the present study was to characterize the effects of bombesin on porcine LES contraction. We used the selective agonists, neuromedin B (NMB), gastrin-releasing peptide (GRP), ...

Two new 2,2'-bipyridine (bpy) derivatives containing ancillary BODIPY chromophores attached at the 5- and 5'-positions (BB3) or 6- and 6'-positions (BB4) were prepared and characterized. In this work, the basic photophysics, electrochemistry, and electrogenerated chemiluminescence (ECL) of BB3 and BB4 are compared with those previously reported for a related bpy-BODIPY derivative (BB2) (J. Phys...

The sonocatalytic performance of the synthesized TiO2/Montmorillonite K10 (TiO2/MMT) nanocomposite was studied in removal of Basic Blue 3 (BB3) from water. The TiO2/MMT nanocomposite was prepared by hydrothermal method. Scanning electron microscope, X-ray diffraction and Fourier transform infrared were used to characterize the synthesized nanocomposite. The average size of TiO2 nanoparticles de...
