... Intestinal inflammation in poultry is a complex response that involves immune and intestinal cells which is still not fully understood. Thus, to better understand the mechanisms that drive the chronic intestinal inflammation in fowl we conducted an experiment applying a previously established nutritional model of low-grade chronic intestinal inflammation to evaluate cytokine and chemokine profiles ...
... Noncovalent interactions between biomolecules such as proteins and nucleic acids coordinate all cellular processes through changes in proximity. Tools that perturb these interactions are and will continue to be highly valuable for basic and translational scientific endeavors. By taking cues from natural systems, such as the adaptive immune system, we can design directed evolution platforms that ca ...

Abstract:
... Toll-like receptors (TLRs) are the largest pattern recognition receptors responsible for activating the innate and adaptive immune response against viruses through the release of inflammatory cytokines and antiviral mediators. Viruses are recognized by several TLRs, including TLR8, which is known to bind ssRNA structures. However, the similarities between TLR8 and TLR7 have obscured the distinctiv ...

Abstract:
... Cell death forms an essential component of the antiviral immune response. Viral infection elicits different forms of host cell death, including the lytic and inflammatory cell death modes necroptosis or pyroptosis. The induction of both types of cell death not only eliminates virus-infected cells but also contributes to the development of innate and adaptive immunity through the release of inflamm ...

Abstract:
... The two major subtypes of human T cells, CD4+ and CD8+, play important roles in adaptive immune response by their diverse functions. To understand the structure–function relation at the single cell level, we isolated 2483 CD4+ and 2450 CD8+ T cells from fresh human splenocytes by immunofluorescent sorting and investigated their morphologic relations to the surface CD markers by acquisition and ana ...

Abstract:
... The interferon (IFN) response is the major early innate immune response against invading viral pathogens and is even capable of mediating sterilizing antiviral immunity without the support of the adaptive immune system. Cumulative evidence suggests that the gut microbiota can modulate IFN responses, indirectly determining virological outcomes. This review outlines our current knowledge of the inte ...

Abstract:
... Over the first weeks of life, the neonatal gastrointestinal tract is rapidly colonised by a diverse range of microbial species that come to form the ‘gut microbiota’. Microbial colonisation of the neonatal gut is a well-established regulator of several physiological processes that contribute to immunological protection in postnatal life, including the development of the intestinal mucosa and adapt ...

Abstract:
... Since the discovery of RNA-programmable nucleases from the prokaryotic adaptive immune system CRISPR–Cas, these proteins have seen rapid and widespread adoption for biotechnological and clinical research. A recently discovered system, CRISPR–Cas13, uses CRISPR RNA guides to target RNA. Interestingly, RNA targeting by Cas13 results in cleavage of both target RNA and bystander RNA. This feature has ...

Abstract:
... Agnathans possess a convergent adaptive immune system in comparison to that of jawed vertebrates. In lieu of immunoglobulins, agnathans deploy variable lymphocyte receptors (VLRs), single chain protein effector molecules consisting of leucine rich repeat modules. Foundational work for this discovery utilized the parasitic sea lamprey, Petromyzon marinus. However, for several reasons, it is desirab ...

Abstract:
... Mass spectrometry-based immunopeptidomics is the method of choice for characterizing human leukocyte antigen binding peptides (HLAp) which play a key role in adaptive immunity. Recently two studies [1,2] reported that a large portion (20-40%) of HLAp’s originate from proteasomal splicing events. Both studies used large-scale mass spectrometry measurements of HLAp’s and bioinformatics analysis: the ...

Abstract:
... Lagovirus europaeus/GI.1 causes a fatal viral condition in rabbits characterized by acute viral hepatitis and disseminated intravascular coagulation. Due to rapid viral and environmental changes variants (Lagovirus europaeus/GI.1a and GI.2) have appeared and few immunological studies were performed. The aim of the study was to determine innate and adaptive immunity parameters in rabbits infected w ...

Abstract:
... Silica nanoparticles (SiNPs) cause pulmonary fibrosis through a complex immune response, but the underlying mechanisms by which SiNPs interact with T cells and affect their functions remain unclear. The T cell receptor (TCR) repertoire is closely related to T cell activation and proliferation and mediates innate and adaptive immunity. High-throughput sequencing of the TCR enables comprehensive mon ...

Abstract:
... The clustered regularly interspaced short palindromic repeats (CRISPR)-Cas systems constitute the adaptive immune system in prokaryotes that provide resistance against invasive genetic elements. The genus Propionibacterium comprises gram-positive, facultative anaerobe, non-spore-forming bacteria, and is the source of some B group vitamins such as B12 as well as bacteriocins. Some of the selected s ...

Abstract:
... Glioblastoma is a devastating primary brain tumor with a median overall survival of approximately 15 months despite the use of optimal modern therapy. While GBM has been studied for decades, modern therapies have allowed for a reduction in treatment-related toxicities, while the prognosis has largely been unchanged. Adjuvant stereotactic radiosurgery (SRS) was previously studied in GBM; however, t ...

Abstract:
... AIDS restriction genes (ARGs) like APOBEC3, TRIM5α, and BST2 can act as immunological detectors of the innate protective mechanism of the body. ARGs influence the course of viral pathogenesis and progression of the disease. The infection caused by different viruses including HIV activates the innate immune receptors leading to production of proinflammatory cytokines, interferons and signals that r ...

... The bovine afferent lymphatic cannulation model allows collection of large volumes of afferent lymph and provides an opportunity to study lymphatic cells trafficking from the periphery directly ex-vivo. The technique requires surgical intervention, but influence of the procedure or time post-surgery on cells trafficking in the lymph has not been well documented. Here, we measured the volume of lym ...

Abstract:
... In mammals, plant lectinshave been shown to possess immunomodulatory properties, acting in both the innate and adaptive immune system to modulate the production of mediators of the immune response, ultimately improving host defences. At present, knowledge of immunomodulatory effects of plant lectins in insects is scarce. Treatment of insect cells with the Orysa sativa lectin, Orysata, was previous ...

Abstract:
... Cathepsins are lysosomal enzymes that participate in important physiological processes, such as development, tissue remodelling, senescence and innate and adaptive immunity. The description of these proteins in molluscs is fragmented and incomplete. In the present work, we identified most of the cathepsin family members in the bivalve Mytilus galloprovincialis by screening published genomic and tr ...

Abstract:
... T cell activation initiates protective adaptive immunity, but counterbalancing mechanisms are critical to prevent overshooting responses and to maintain immune homeostasis. The CARD11-BCL10-MALT1 (CBM) complex bridges T cell receptor engagement to NF-κB signaling and MALT1 protease activation. Here, we show that ABIN-1 is modulating the suppressive function of A20 in T cells. Using quantitative ma ...
