STING (stimulator of IFN genes) activates the IFN-dependent innate immune response to infection on sensing the presence of DNA in cytosol. The quantity of STING accumulating in cultured cells varies; it is relatively high in some cell lines [e.g., HEp-2, human embryonic lung fibroblasts (HEL), and HeLa] and low in others (e.g., Vero cells). In a preceding publication we reported that STING was ...

Tibetan pig is well known for its strong disease resistance. However, little is known about the molecular basis of its strong resistance to disease. Stimulator of interferon (IFN) genes (STING), also known as MPYS/MITA/ERIS/TMEM173, is an adaptor that functions downstream of RIG-I and MAVS and upstream of TBK1 and plays a critical role in type I IFN induction. Here we report the first cloning a...

Innate immunity to viral infection involves induction of the type I IFN response; however, dysfunctional regulation of this pathway leads to inappropriate inflammation. Here, we evaluated a nonconsanguineous family of mixed European descent, with 4 members affected by systemic inflammatory and autoimmune conditions, including lupus, with variable clinical expression. We identified a germline do...

PURPOSE Postmastectomy irradiation provides an excellent model for irradiated skin care practices because of the relatively uniform surface and radiation compared with other situations in which radiation-induced moist desquamation is common. We designed a study to test the effect of prophylactic 3M Cavilon No-Sting Barrier Film (No-Sting) on the rates of moist desquamation compared with sorbole...

Immunotherapy is one of the key strategies for cancer treatment. The cGAS-cGAMP-STING-IRF3 pathway of cytosolic DNA sensing plays a pivotal role in antiviral defense. We report that the STING activator cGAMP possesses significant antitumor activity in mice by triggering the STING-dependent pathway directly. cGAMP enhances innate immune responses by inducing production of cytokines such as inter...

Detection of foreign materials is the first step of successful immune responses. Stimulator of interferon genes (STING) was shown to directly bind cyclic diguanylate monophosphate (c-di-GMP), a bacterial second messenger, and to elicit strong interferon responses. Here we elucidate the structural features of the cytosolic c-di-GMP binding domain (CBD) of STING and its complex with c-di-GMP. The...

Acute Kidney Injury in children following bee sting envenomation is rare and survival is hinged on early recognition and prompt appropriate management. This report is aimed at raising awareness among healthcare workers, of one of the systemic effects of massive bee sting and the need to develop sting treatment protocol. A three year old preschooler was attacked by a swarm of bees, receiving ove...

The flavonoids FAA and DMXAA showed impressive activity against solid tumors in mice but failed clinical trials. They act on a previously unknown molecular target(s) to trigger cytokine release from leukocytes, which causes tumor-specific vascular damage and other antitumor effects. We show that DMXAA is a competitive agonist ligand for mouse STING (stimulator of interferon genes), a receptor f...

An attempt has been made in this communication to develop antiserum in rabbit against Scatophagus. argus sting extract. Antiserum did not neutralized the sting extract induced proinflammatory and haemorrhagic activity but successfully neutralized lethality upto 2LD50. Cyproheptadine, indomethacin and BW 755C pretreatment significantly reduced sting extract induced proinflammatory activity. The ...

A wide variety of neurological syndromes have been described following hymenoptera sting like encephalopathy, myeloradiculopathy, optic neuropathy, seizures, parkinsonism, exacerbation of multiple sclerosis, myasthenia gravis, encephalomyelopolyradiculoneuritis and obsessive compulsive behaviour. While petechial haemorrhages, cerebral edema, meningeal hyperemia and intraventricular haemorrhage ...
