Gene-engineered immune cell therapies have partially transformed cancer treatment, as exemplified by the use of chimeric antigen receptor (CAR)-T cells in certain hematologic malignancies. However, there are several limitations that need to be addressed target more types. Natural killer (NK) a type innate represent unique biology surveillance. In particular, NK obtained from heathy donors can s...

Transient stimulation with substance P (SP) induces endocytosis and recycling of the neurokinin-1 receptor (NK(1)R). The effects of sustained stimulation by high concentrations of SP on NK(1)R trafficking and Ca(2+) signaling, as may occur during chronic inflammation and pain, are unknown. Chronic exposure to SP (100 nm, 3 h) completely desensitized Ca(2+) signaling by wild-type NK(1)R (NK(1)Rw...

Shark cartilage is considered as a natural dietary supplement consisting of anti-angiogenic, immunostimulatory, and anti-inflammatory characteristics. Therefore, this study was designed to inspect the possibility that whitecheek shark (Carcharhinus dussumieri) cartilage proteins motivate expression of NKG2D, CXCR3, NKP46, and NKP44 receptors on natural killer cells and their activities against ...

Development of natural killer (NK) cells is thought to depend on interactions between NK progenitors and the bone marrow (BM) microenvironment; however, little is known about the molecular signals involved. Here we show that lymphotoxin (LT) provides an important signal for the development of both NK cells and NK/T cells. LTalpha-/- mice show marked reduction in splenic and BM NK and NK/T cell ...

Background Nasopharyngeal carcinoma, common in Southeast Asia, is mainly a non-keratinizing, squamous cell carcinoma (NK-NPC) and clinically heterogeneous. Methods Herein, we analyzed three human gene expression microarray datasets characterizing 81 NK-NPC tumors and 21 normal nasopharyngeal (NP) tissues to identify molecular subtypes of NK-NPC. In one of the datasets, QRT-PCR measurement of ex...

The study object is a prototype of composite bridge prestressed concrete beam with length 42.0 m for road desks perception impact from motor vehicles in the form A14, NK-120 and NK-180 loads.
