Abstract
Vaccination is deemed the best approach against the COVID-19 pandemic. In regard of safety and protectivity, the whole inactivated vaccine platform is advantageous and widely used. Whole inactivated vaccine provides broader protection against various antigenic components of SARS-CoV-2. This study aims to analyze the immune response of cynomolgus macaques (Macaca fascicularis) following inactivated SARS-CoV-2 vaccine administration. The analysis utilized the flow cytometry and enzyme-linked immunosorbent assay to evaluate CD59 NK cell expression and serum IL-6 level. This research used 6 macaques which were divided into 2 groups: Adult and Adolescence. Each group was consisted of 3 macaques. The macaques received two doses of 3 µg of inactivated SARS-CoV-2 vaccine with 21 days interval between first and second dose. CD59 and IL-6 level were measured before the first vaccination (D0), 21 days post-vaccination but before second dose (D21), and 14 days after the second dose (D35). The result showed significant escalation (p ≤ 0.05) of CD59 NK cell expression between D0, D21, and D35 in both adult and adolescence macaques. Higher expression of CD59 NK cell was found in adult macaques compared to adolescence macaques. Meanwhile, the level of IL-6 remained constant (p > 0.05) throughout D0, D21, and D35 in both groups. In conclusion, the inactivated SARS-CoV-2 vaccine candidate can increase CD59 NK cell expression significantly, while IL-6 level was mildly elevated although the differences were insignificant.

Abstract
Abstract
Background: Tumor characterization through the study of molecular biology has become an invaluable tool in understanding cancer development and evolution due to its relationship with chromosomal mutations, alterations or aberrations. The purpose of this study was to investigate the involvement of genes such as TLR-4 and DNA repair pathways (XRCC1 and XPD) in laryngeal cancer susceptibility in a Romanian population. Method: We performed a case-control study on 157 laryngeal cancer patients and 101 healthy controls. Genetic testing was carried out using Polymerase Chain Reaction-Restriction Fragment Length Polymorphism. Results: We identified the Gln allele of the XPDLys751Gln polymorphism as an individual risk factor in laryngeal cancer development (Gln vs Lys, adjusted OR=1.65, 95%CI=1.13–2.40, P=0.008). Subjects with the mutant homozygote variant (Gln/Gln) had a two fold increase in cancer risk (adjusted OR=2.18, 95%CI=1.06–4.47, p=0.028) when compared to the reference wild type genotype (Lys/Lys). Stratification by sex and age, identified males under 62 years as the most susceptible group with an almost three fold risk (adjusted OR=2.94, 95%CI=1.31–6.59, p=0.007) for the dominant model (Lys/Gln+Gln/Gln). No associations were found for TLR-4Thr399Ile, XRCC1Arg194Trp and XRCC1Arg399Gln. Conclusion: The results of the study show that the XPDLys751Gln polymorphism may be among other independent risk factors for developing laryngeal cancer where as TLR-4Thr399Ile, XRCC1Arg194Trp and XRCC1 Arg399Gln show no such association. However, we consider the relative small number of the subjects selected for this analyses a possible limitation towards the real influence the obtain results may pertain in laryngeal cancer evolution.

Abstract
Pattern recognition receptors (PRRs) are members of innate immunity, playing pivotal role in several immunological reactions. They are known to act as a bridge between innate and adaptive immunity. They are expressed on several normal cell types but have been shown with increasing frequency on/in tumor cells. Significance of this phenomenon is largely unknown, but it has been shown by several authors that they, predominantly Toll-like receptors (TLRs), act in the interest of tumor, by promotion of its growth and spreading. Preparation of artificial of TLRs ligands (agonists) paved the way to use them as a therapeutic agents for cancer, so far in a limited scale. Agonists may be combined with conventional anti-cancer modalities with apparently promising results. PRRs recognizing nucleic acids such as RIG-1 like receptors (sensing RNA) and STING (sensing DNA) constitute a novel promising approach for cancer immunotherapy.

Abstract
Objective To evaluate the radiosensitivity effect of CpG oligodeoxyribonucleotide (ODN)
7909 on human epidermoid cancer strain-2 (Hep-2) cells in
vitro and discuss the potential for improved radiotherapy
treatment in patients with laryngeal squamous cell carcinoma. Methods Toll-like receptor (TLR) 9 expression was assessed in Hep-2
cells using Western blots and reverse transcription polymerase chain
reaction. Cell Counting Kit-8 was used to detect Hep-2 cell viability at 24
and 48 h following treatment with different CpG ODN7909 concentrations.
Cellular colonization was evaluated using microscopy. Cell cycle
distribution and apoptosis rate was determined with flow cytometry.
Interleukin (IL)-12 and tumour necrosis factor (TNF)-α concentrations were
detected by enzyme-linked immunosorbent assay. Results Hep-2 cells were found to express TLR9, and CpG ODN7909
treatment suppressed Hep-2 cell viability in a dose- and time-dependent
manner. Cell survival curve analyses revealed a sensitivity enhancement
ratio of the mean death dose of 1.225 for CpG ODN7909 plus irradiation
versus irradiation alone. Furthermore, the population of Gap 2/mitotic-phase
cells, apoptosis rate and secreted IL-12 and TNF-α levels were significantly
increased in Hep-2 cells treated with CpG ODN7909 plus irradiation versus IR
alone. Conclusion CpG ODN7909 enhanced the radiosensitivity of Hep-2 cells in
vitro.

Abstract
Background Toll-like receptor 2 (TLR2), an important pattern recognition receptor, activates proinflammatory pathways in response to various pathogens. It has been reported in humans and chicken, but not in geese, an important waterfowl species in China. Since some vaccines stimulate robust immune responsesl in chicken but not in geeeses we speculated that their immune systems are different. Results In this study, we cloned the goose TLR2-1 gene using rapid amplification of cDNA ends (RACE)and showed that geese TLR2-1 encoded a 793-amino-acid protein, containing a signal secretion peptide, an extracellular leucine-rich repeat domain, a transmembrane domain and a Toll/interleukin-1 receptor signaling domain deduced from amino acid sequence. TLR2-1 shared 38.4%–93.5% homology with its homologues in other species. Tissue expression of geese TLR2-1 varied markedly, and was higher in kidney, cloacal bursa, skin and brain compared to other organs/tissues. HEK293 cells transfected with plasmids carrying goose TLR2-1 and NF-κB-luciferase responded significantly to stimulation with Mycoplasma fermentans lipopeptide. Furthermore, geese infected with Mycoplasma gallisepticum (MG) and Salmonella enteritidis (SE) showed significant upregulation of TLR2-1 in both in vivo and in vitro. Conclusion Geese TLR2-1 is a functional homologue of TLR2 present in other species and plays an important role in bacterial recognition in geese.

Abstract
Melanoma is one of the cancers of fastest-rising incidence in the world. Inducible nitric oxide synthase (iNOS) is overexpressed in melanoma and other cancers, and previous data suggest that iNOS and nitric oxide (NO) drive survival and proliferation of human melanoma cells. However, specific mechanisms through which this occurs are poorly defined. One candidate is the PI3K-AKT-mTOR pathway, which plays a major role in proliferation, angiogenesis, and metastasis of melanoma and other cancers. We used the chick embryo chorioallantoic membrane (CAM) assay to test the hypothesis that melanoma growth is regulated by iNOS-dependent mTOR pathway activation. Both pharmacologic inhibition and siRNA-mediated gene silencing of iNOS suppressed melanoma proliferation and in vivo growth on the CAM in human melanoma models. This was associated with strong downregulation of mTOR pathway activation by Western blot analysis of p-mTOR, p70 ribosomal S6 kinase (p-P70S6K), p-S6RP, and p-4EBP1. iNOS expression and NO were associated with reversible nitrosylation of tuberous sclerosis complex (TSC) 2, and inhibited dimerization of TSC2 with its inhibitory partner TSC1, enhancing GTPase activity of its target Ras homolog enriched in brain (Rheb), a critical activator of mTOR signaling. Immunohistochemical analysis of tumor specimens from stage III melanoma patients showed a significant correlation between iNOS expression levels and expression of the mTOR pathway members. Exogenously supplied NO was also sufficient to reverse the mTOR pathway inhibition by the B-Raf inhibitor vemurafenib. In summary, covalent modification of TSC2 by iNOS-derived NO is associated with impaired TSC2/TSC1 dimerization, mTOR pathway activation, and proliferation of human melanoma. This model is consistent with the known association of iNOS overexpression and poor prognosis in melanoma and other cancers.
