Researchers at The University of Texas MD Anderson Cancer Center have developed an ultrasound-guided cancer immunotherapy platform that generates systemic antitumor immunity and improves the therapeutic efficacy of immune checkpoint blockade. The findings from the preclinical study were published today in Nature Nanotechnology. As the first-of-its-kind platform, the Microbubble-assisted UltraSound-guided…

Graphical abstract. Credit: Cell Reports (2022). DOI: 10.1016/j.celrep.2022.110856 The body’s innate immune system, active from birth, is the first line of defense against viruses and other pathogens that cause disease. Using vaccination as an example, after receiving a vaccine, pain, redness, or swelling may occur at the injection site. This…

The gut microbiota is crucial for health. However, how these non-invasive microbes communicate with the rest of the body to improve host physiology is not fully understood. Researchers from Stockholm, Umea, and Gothenburg Universities, Sweden, claim that the gut microbiota is essential for natural resistance to viral infections. This evidence…

Infection with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that led to the coronavirus disease 2019 (COVID-19) pandemic can cause various clinical presentations ranging from asymptomatic and mild disease to critical and even deadly outcomes. The pathogenesis of COVID-19 is directly associated with the destruction of lung epithelial cells,…

Atrophic (“dry”) form of age-related macular degeneration (AMD) is a leading cause of vision loss characterized by macular retinal pigment epithelium (RPE) and the ensuing photoreceptor degeneration. cGAS-STING signaling is a key cytosolic DNA sensor system in innate immunity and have recently been shown promotes RPE degeneration. However, expression regulation…

Sam50 is a key component of the sorting and assembly machinery (SAM) complex and is also involved in bridging mitochondrial outer and inner membrane contacts. However, the physiological and pathological functions of Sam50 remain largely unknown. On March 21, 2022, Wuhan University Song Zhiyin and Meng Qingtao jointly published a…

Abstract The cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) signaling exert essential regulatory function in microbial-and onco-immunology through the induction of cytokines, primarily type I interferons. Recently, the aberrant and deranged signaling of the cGAS-STING axis is closely implicated in multiple sterile inflammatory diseases, including heart failure, myocardial infarction,…

The innate immune system has a critical role in the recognition and response to extracellular and intracellular pathogens. Pattern recognition receptors including Toll-like receptors (TLRs), C-type lectin receptors (CLRs), RIG-I-like receptors (RLRs), NOD-like receptors (NLRs), and cyclic guanosine monophosphate-adenosine monophosphate synthase (cGAS) are responsible for recognizing these pathogens. cGAS…

The human immune system, that marvel of complexity, subtlety, and sophistication, includes a billion-year-old family of proteins used by bacteria to defend themselves against viruses, scientists at Dana-Farber Cancer Institute and in Israel have discovered. The findings, published online today by the journal Science, are the latest in a growing…

Significance Interferon (IFN)-mediated antiviral responses serve as the first line of the host innate immune defense against viral infection. Here we identify a previously uncharacterized protein designated phospholipase A2 inhibitor and LY6/PLAUR domain-containing protein (PINLYP), which is essential for embryonic development and plays an important role in type I IFN…

The cGAS-STING pathway is a key component of the innate immune system and exerts crucial roles in the detection of cytosolic DNA and invading pathogens. Accumulating evidence suggests that the intrinsic cGAS-STING pathway not only facilitates the production of type I interferons (IFN-I) and inflammatory responses but also triggers autophagy….

Just as a home security system can alert a homeowner to the presence of an intruder, a protein called polyglutamine binding protein-1 (PQBP1) found in brain cells can alert the body to the presence of “intruding” viruses like human immunodeficiency virus (HIV). Now, researchers in Japan have shed new light…

Introduction Invaded by exogenous or endogenous pathogens, the host immune system will be activated accordingly to resist harm and maintain homeostasis, which includes innate immunity and adaptive immunity. As the first line of host immune defense, innate immunity plays a critical role in recognizing extracellular and intracellular pathogens (1, 2)….
