T47 |
0-236 |
Sentence |
denotes |
The binding of the cytokine to its transmembrane cell surface receptor activates an intracellular signal transduction pathway, generally a Janus kinase (Jak), which, via a kinase cascade, phosphorylates its transcription protein (STAT). |
T48 |
237-326 |
Sentence |
denotes |
Phosphorylated STAT dimers and moves to the nucleus, initiating a new gene transcription. |
T49 |
327-822 |
Sentence |
denotes |
Mutation of STAT1 increases susceptibility to virus infections because it is involved in various signalling pathways, including IFN-α/β, IFN- γ, IFN-l, IL-2, IL-3, IL-6, IL-9, IL-10, IL-11, IL-12, IL-15, IL-21, IL-22, IL-26 and IL-27 [10], and chemokines of several types such as C-X-C motif chemokine ligand 10 (CXCL-10), Regulated upon Activation, Normal T Cell Expressed and Presumably Secreted (RANTES)/Chemokine (C–C motif) ligand 5 (CCL-5), Monocyte Chemoattractant Protein-1 (MCP-1) [11]. |
T50 |
823-916 |
Sentence |
denotes |
IFN-γ promotes antigen-specific antibody production, increasing the activity of phagocytosis. |
T51 |
917-1088 |
Sentence |
denotes |
In the meantime, PRRs trigger inflammatory signalling, with activation of transcription factors like nuclear factor kappa-light-chain-enhancer of activated B cells (NFκB). |
T52 |
1089-1456 |
Sentence |
denotes |
NFκB is the key transcriptional regulator of many pro-inflammatory cytokines, adhesion molecules, chemokines, growth factors and other mediators of inflammation, as tumour necrosis factor (TNF), interleukins 1 (IL-1β), 6 (IL-6), and 12 (IL-12), promotes cellular proliferation and protects against apoptosis providing a mechanism that determines chronic inflammation. |
T53 |
1457-1564 |
Sentence |
denotes |
The recognition of pathogens is achieved through the presence of pattern recognition receptors (PRRs) [12]. |
T54 |
1565-1667 |
Sentence |
denotes |
PRRs identify the microbe-associated molecular patterns (MAMPs), and defensive responses is activated. |
T55 |
1668-1803 |
Sentence |
denotes |
PRRs include Toll-like receptors (TLRs), that are able to recognize viral DNA, viral double-stranded RNA and viral single-stranded RNA. |
T56 |
1804-1917 |
Sentence |
denotes |
TLRs are expressed on macrophages, dendritic cells, neutrophils, eosinophils, epithelial cells and keratinocytes. |
T57 |
1918-2041 |
Sentence |
denotes |
In particular, intracellular TLR-7 and TLR-8 allow the innate recognition of the single-stranded RNA of coronaviruses [13]. |
T58 |
2042-2200 |
Sentence |
denotes |
Intracellular and extracellular PRRs recognized spike glycoprotein, of the coronavirus coat, starting the inflammatory process, through the NFκB pathway [14]. |
T59 |
2201-2418 |
Sentence |
denotes |
Moreover, Nucleotide-Binding Domain, Leucine-Rich Repeat (NLR) proteins have also been identified, and NALP3 (NACHT, LRR and PYD domains-containing protein 3) has a special function in the innate immune response [15]. |
T60 |
2419-2483 |
Sentence |
denotes |
The processes involved in antiviral immunity is shown in Fig. 1. |
T61 |
