Varicella Zoster Virus (VZV) is a human-restricted α-herpesvirus that exhibits tropism for the skin. The VZV host receptors and downstream signaling pathways responsible for the antiviral innate immune response in the skin are not completely understood. Here, we show that stimulator of interferon genes (STING) mediates an important host defense against VZV infection in dermal cells including human dermal fibroblasts (HDFs) and HaCaT keratinocytes. Inhibition of STING using small interfering RNA (siRNA) or short hairpin RNA (shRNA)-mediated gene disruption resulted in enhanced viral replication but diminished IRF3 phosphorylation and induction of IFNs and pro-inflammatory cytokines...

Various ocular and systemic reactions have been associated with insect sting. However, insect stings have been rarely reported to cause exotropia and diplopia. We encountered exotropia in a 6-year-old child with rhabdomyolysis of the left lower extremities caused by an insect sting. Exotropia and diplopia developed within 1 day after the sting and improved completely 1 week after the onset of symptoms. Clinicians should be aware of the potential for the development of exotropia in patients with insect stings, which requires careful follow-up...

While STING (STimulator of INterferon Genes) has been shown to be essential for cytosolic DNA-triggered innate immune activation, accumulated evidence obtained from various studies suggested that an intrinsic relevance of STING-associated signaling in tumorigenesis can be observed. Also, several clinical trials using immunostimulatory adjuvants, particularly agonistic as well as non-agonistic ligands for STING, have revealed their therapeutic potential not only as vaccine adjuvants but also as anti-tumor agents...

Allergen immunotherapy (AIT) is the only treatment that works on the causes of allergy. Available AIT nowadays are subcutaneous immunotherapy (SCIT) and sublingual immunotherapy (SLIT) for allergic rhinitis and asthma, while for allergy to Hymenoptera venom only subcutaneous route is recommended. A bulk of trials and meta-analyses demonstrated that efficacy and safety of AIT in decreasing allergic clinical symptoms and use of rescue medications, while its preventive capacity is yet under investigation. The most important of these effects is the prevention of potentially fatal anaphylactic reactions to Hymenoptera stings by venom immunotherapy (VIT)...

Scorpion envenomation is a public health problem, especially in tropical and subtropical countries. Considering the high incidence of scorpionism in some areas, pregnant women and nursing mothers may be possible victims. Scorpion stings alter the release of neurotransmitters and some cytokines. These mediators act as organizers and programmers in the adequate formation of the nerves, and non-physiological concentrations of them during the brain organization originate disorders and diseases that can appear later in the life of the individual...

The STING (Stimulator of Interferon Genes) protein connects microorganism cytosolic sensing with effector functions of the host cell by sensing directly cyclic dinucleotides (CDNs), originating from pathogens or from the host upon DNA recognition. Although STING activation favors effective immune responses against viral infections, its role during bacterial diseases is controversial, ranging from protective to detrimental effects for the host. In this review, we summarize important features of the STING activation pathway and recent highlights about the role of STING in bacterial infections by Chlamydia, Listeria, Francisella, Brucella, Shigella, Salmonella, Streptococcus, and Neisseria genera, with a special focus on mycobacteria...

Stimulator of interferon genes (STING) was initially described as a sensor of intracellular bacterial and viral DNA and a promising adjuvant target in innate immune cells; more recently STING has also been shown to detect endogenous DNA and play a role in tumor immunity and autoimmune disease development. Thus far STING has been studied in macrophages and dendritic cells. In this study, to our knowledge we provide the first evidence of STING activation in T cells, in which STING agonists not only provoke type I IFN production and IFN-stimulated gene expression, mirroring the response of innate cells, but are also capable of activating cell stress and death pathways...

Jellyfish stinging capsules known as nematocysts are explosive, natural-injection systems with high potential as a natural drug-delivery system. These organelles consist of a capsule containing a highly folded thin needle-like tubule and a matrix highly concentrated with charged constituents that enable the tubule to fire and penetrate a target. For the purpose of using these nematocysts as drug delivery system it is first required to purify sub-populations from heterogeneous population of capsules and to investigate each subpopulation's distinct function and characteristics...

The application of insect and arthropod information to medicolegal death investigations is one of the more exacting applications of entomology. Historically limited to homicide investigations, the integration of full time forensic entomology services to the medical examiner's office in Harris County has opened up the opportunity to apply entomology to a wide variety of manner of death classifications and types of scenes to make observations on a number of different geographical and species-level trends in Harris County, Texas, USA...

Stings of hymenoptera can induce IgE-mediated hypersensitivity reactions in venom-allergic patients, ranging from local up to severe systemic reactions and even fatal anaphylaxis. Allergic patients' quality of life can be mainly improved by altering their immune response to tolerate the venoms by injecting increasing venom doses over years. This venom-specific immunotherapy is highly effective and well tolerated. However, component-resolved information about the venoms has increased in the last years. This knowledge is not only able to improve diagnostics as basis for an accurate therapy, but was additionally used to create tools which enable the analysis of therapeutic venom extracts on a molecular level...

Cingulate epilepsy is a rare form of epilepsy. Seizures from the anterior cingulate may present with mood change, fear, hypermotor activity, and autonomic signs, while posterior cingulate seizures resemble temporal lobe seizures. We describe a child with cingulate epilepsy who experienced unpleasant/painful sensory phenomenon. The sensations were described as spiders crawling on his forehead/right leg, ladybugs causing right ear pain and bees stinging his head/right extremities. Unpleasant sensory phenomenon/pain are rarely reported in cingulate epilepsy...

Stimulator of interferon genes (STING) is a DNA sensor and an important cytoplasmic adaptor for other DNA sensors, such as Z-DNA binding protein 1 (DAI), DEAD-box helicase 41 (DDX41), and interferon-γ-inducible protein 16 (IFI16). The activation of STING signaling leads to the production of type I interferons and some other pro-inflammatory cytokines, which are critical for host defense against viral infection. Recent accumulating evidences suggest that STING is also involved in tumor development. However, the role of STING signaling in tumorigenesis is complicated, and a comprehensive review is still lacking...
