Abstract
The therapeutic efficacy of natural killer (NK) cells-based immunotherapy is greatly related with the survival of transplanted NK cells. However, no effective strategy was reported to monitor NK cell viability in adoptive immunotherapy in vivo. Herein, we develop a ratiometric NIR-II fluorescence imaging strategy to quantitively track and visualize the adoptive NK cell viability in vivo in real-time. The nanoprobe consists of lanthanide-based down-conversion nanoparticles (DCNP) coated with IR786s, a reactive oxygen species (ROS) sensitive to NIR dye, which was directly labeled with NK cells. Upon cell death, the excessive ROS generation occurred within NK cells, along with IR786s degradation, turning on NIR-II fluorescent signal at 1550 nm of DCNP under 808-nm excitation, while the fluorescent signal at 1550 nm of DCNP under 980-nm excitation was stable. Such an intracellular ROS-induced ratiometric NIR-II fluorescent signal was validated to correlate well with NK cell viability in vivo. Using this nanoreporter, we further demonstrated that co-treatment with IL-2, IL-15, and IL-21 could improve NK cell viability in vivo, achieving enhanced immunotherapy for orthotopic hepatocellular carcinoma. Overall, this strategy allows for longitudinal and quantitative tracking of NK cell viability in NK cell-based immunotherapy.

Abstract
INTRODUCTION Hot tub lung (HTL) is a hypersensitivity pneumonitis (HP) related to inhalation of non-tuberculous mycobacteria (NTM) when exposed to ejected jet droplets from a jacuzzi. The aetiological debate is not completely settled in the literature. METHOD An observational study of 14 cases of HTL, diagnosed at the University Hospital of Besançon, France, between 2004 and 2018 according to the diagnostic criteria used in the clinic. RESULTS This cohort corresponds to type I HP (inflammatory), with one case of type II HP. Decrease of lung transfer for carbon monoxide was present in 86% of examinations (n=12/14). In total, 84% of bronchoalveolar lavages showed a lymphocytic cellular pattern≥30% (n=11/13). The environmental survey enabled the identification of NTM in 93% of cases (n=13/14), mainly Mycobacterium avium. Serum precipitins directed against NTM were found in 10% of the cases (n=2/20). Three cases received corticosteroid therapy and none received antibiotics. Antigenic eviction has improved the symptomatology in all cases. CONCLUSIONS Our cohort supports the hypothesis that HTL is predominantly a type I HP. Avoidance of the agent involved (NTM) is necessary. The diagnosis is difficult because serum precipitins against NTM are not easily demonstrable. An environmental survey could facilitate the identification of the NTM. Prevention of HTL depends on education of the clinician and the patient.

Abstract
The lack of vaccine adjuvants that are able to induce robust T cell responses fosters the search for more powerful options. Pathogen-like particles are a promising approach. The adjuvant activity of pathogen-like particles is highly influenced by size and surface composition. This study aimed to evaluate the adjuvant potential of two different β-glucan-based particles, blend chitosan/β-glucan particles (ChiGluPs), which are positively charged and have mean size of 1276 nm, and neutral yeast-derived glucan particles (GPs), with a mean size of 3 μm. Additionally, chitosan particles (ChiPs) were used to understand the effect of β-glucan addition (ChiGluPs). Mouse spleen cells responded through the production of either TNF-α or RANTES, following in vitro stimulation with particles containing either β-glucan (ChiGluPs and GPs) or chitosan (ChiGluPs and ChiPs). Human monocytes responded to all particles through TNF-α secretion. Subcutaneous vaccination of mice with the hepatitis B surface antigen (HBsAg) showed increased serum IgG for all particles compared to HBsAg alone (435-, 4500-, or 2500-fold increase for either ChiPs, ChiGluPs, or GPs). Interestingly, only GPs elicited the secretion of HBsAg-specific Th1, Th2, Th9, Th17, Th22, and Treg-related cytokines. This study demonstrates, for the first time, that GPs can have a significant role against the hepatitis B virus by favoring antiviral immunity.

Abstract
The development of new vaccine adjuvants is urgently needed not only to enable new routes of vaccine administration but mostly to go beyond protective humoral immunity, often insufficient to fight infectious diseases. The association of two or more immunopotentiators or mimicking pathogen physicochemical properties are strategies that can favor powerful and more balanced Th1/Th2 immune responses. Therefore, the present work aimed to combine both chitosan and β-glucan biopolymers in the same particle, preferably with surface β-glucan localization to simulate the cell wall of some pathogens and to stimulate the immune cells expressing the Dectin-1 receptor. Chitosan:β-glucan particles (ChiGluPs) were developed through a chitosan precipitation method. The chitosan was precipitated into a β-glucan alkaline solution followed by genipin crosslink. The optimized method produced particles with a mean diameter of 837 nm for ChiPs and 1274 nm for ChiGluPs. β-glucan surface location was confirmed by zeta potential measurements (+24 mV for ChiGluPs and +36 mV for ChiPs) and zeta potential titration. These new particles showed high antigen loading efficacy and low cytotoxicity. Mice vaccination studies revealed that both ChiPs and ChiGluPs had an adjuvant effect for the hepatitis B surface antigen (HBsAg), with ChiGluPs resulting in serum anti-HBsAg total IgG 16-fold higher than ChiPs, when administered with 1.5 µg HBsAg per dose. Specifically, IgG1 subclass was 5-fold higher and IgG3 subclass was 4-fold higher for ChiGluPs comparing to ChiPs. Overall, the preparation method developed allowed the advantageous combination of β-glucan with chitosan, without chemical functionalization, which represents an additional step toward tailor-made adjuvants production using simple precipitation techniques.

Abstract
Background Composition of organic dust is very complex, involving particles of microbial, animal and plant origin. Several environmental exposure studies associate microbial cell wall agents in organic dust with various respiratory symptoms and diseases. The aim of the present study was to investigate the in vitro effects of the co-exposure of fungal cell wall agents (FCWAs) and bacterial lipopolysaccharide (LPS) on inflammatory immune responses of peripheral blood mononuclear cells (PBMCs) from patients with pulmonary sarcoidosis. Methods PBMCs from 22 patients with pulmonary sarcoidosis and 20 healthy subjects were isolated and stimulated in vitro with FCWAs (soluble and particulate (1 → 3)-β-D-glucan, zymosan and chitosan) and/or LPS. Subsequently, cytokines were measured by ELISA and the mRNA expression of dectin-1, toll-like receptor 2 (TLR2), TLR4 and mannose receptor (MR) was analysed by real-time RT-PCR. Results Patients with sarcoidosis had a significantly higher secretion of inflammatory cytokines tumour necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), IL-10 and IL-12 (1.7-fold, 2.0-fold, 2.2-fold, and 2.8-fold, respectively; all p < 0.05) after in vitro co-stimulation of PBMCs with FCWAs and LPS. We showed that PBMCs from patients with sarcoidosis had a higher baseline mRNA expression of dectin-1, TLR2, TLR4 and MR (6-fold, 11-fold, 18-fold, and 4-fold, respectively). Furthermore, we found a reduced expression of dectin-1, TLR2 and TLR4 after stimulation with FCWAs and/or LPS, although the reduction was significantly weaker in patients than in healthy subjects. Conclusions In conclusion, co-stimulation with FCWAs and LPS of PBMC from patients with sarcoidosis caused a weaker reduction of dectin-1, TLR2, TLR4 receptors expression, which could increase the sensitivity of PBMCs, leading to excessive inflammatory cytokine responses and result in the development or progression of pulmonary sarcoidosis.

Abstract
BACKGROUND AND OBJECTIVES Sarcoidosis is an inflammatory disease with increased levels of inflammatory cytokines. Previous studies have shown a relation between the degree of granuloma infiltration and serum cytokine levels, except for interleukin- (IL-) 10. The aim of the study was to further investigate the serum levels of IL-10 in patients with sarcoidosis and relate them to fungal exposure in terms of the amount of fungi in the air of their homes and β-glucan in bronchoalveolar lavage (BAL) fluid. METHODS Patients with sarcoidosis (n = 71) and healthy controls (n = 27) were enrolled. IL-10 was determined in serum. BAL was performed and the amount of β-glucan was measured. Domestic exposure to fungi was determined by measuring airborne β-N-acetylhexosaminidase (NAHA) in the bedrooms. RESULTS At high levels of fungal exposure (domestic fungal exposure and β-glucan in BAL), serum IL-10 values were lower than at low and intermediate exposure levels. CONCLUSION The low serum IL-10 values at high fungal exposure suggest that fungal cell wall agents play a role in granuloma formation in sarcoidosis by inhibiting the secretion of the anti-inflammatory cytokine IL-10.

Abstract
BACKGROUND Mould exposure has been linked to childhood asthma and bronchial hyper-responsiveness. Few studies have assessed beta-(1,3)-d-glucan (beta-glucan), a significant fungal cell wall constituent, in relation to asthma in adolescence. OBJECTIVE To determine whether house dust-derived beta-glucan exposure at age 7-10 is associated with the development and persistence of atopic and non-atopic asthma, and bronchial hyper-responsiveness (BHR) by age 11-14. METHODS Dust samples were collected from the 1995 Study of Asthma, Genes, and Environment (SAGE) birth cohort. This cohort was derived from Manitoba provincial healthcare administrative records of children high and low risk for asthma. Samples were collected from the homes of 422 children at age 7-10 and analyzed using beta-glucan and endotoxin-specific Limulus Amoebocyte Lysate assays. Asthma, atopy, and BHR status of each child were also assessed at ages 7-10 and 11-14. RESULTS At age 7-10, beta-glucan dust levels in the home were associated with persistent atopic asthma at age 11-14 (OR 1.79 for each unit increase in levels, 95% CI 1.14-2.81), independent of endotoxin exposure, and Alternaria or Cladosporium sensitization. The likelihood of BHR almost doubled with unit increases in dust beta-glucan in asthmatic children. In children without asthma, exposure to high beta-glucan levels at age 7-10 also elevated risk for BHR in adolescence (OR 1.74, 95% CI 1.05-2.89). New-onset atopic asthma was twice more likely following high beta-glucan exposure in children without asthma but the association did not reach statistical significance. No associations were evident with concurrent asthma phenotype at age 7-10 or non-atopic asthma at age 11-14. CONCLUSION These findings implicate home beta-glucan exposure at school-age as a risk factor for persistent atopic asthma and new-onset BHR. The higher prevalence of BHR in urban adolescents may be propagated by this home exposure.

Abstract
β-glucans are a group of biologically active polysaccharides of natural origin with a proven pleiotropic immunomodulation effect. Their efficacy has been confirmed in the therapeutic treatment and prevention of various infectious diseases, secondary immune defects and also of oncologic disorders. Allergic diseases are one of the most frequent diseases and their prevalence continues to increase. They develop as a consequence of dysregulation of the immune system, especially when there is failure in the equilibrium of the response of TH1/TH2 lymphocytes towards TH2. New therapeutic approaches in the treatment of immunopathological conditions (e.g. allergic or oncologic) are directed to restoring the equilibrium among different T lymphocyte subpopulations. Based on in vitro experiments, and also on animal and human clinical studies, there is much evidence for the importance of β-glucans in the treatment and also prevention of allergic diseases; this opens new perspectives on the use of this widespread and popular group of natural substances.

Abstract
Dermatophytes invade the stratum corneum of the skin and other keratinized tissues such as hair and nails, and Trichophyton rubrum causes approximately 80% of cutaneous mycoses in humans. To evaluate the cellular immune response of patients with extensive dermatophytosis caused by T. rubrum, we evaluated lymphocyte populations, the lymphoproliferative response to: phytohaemagglutinin (PHA); anti-CD3 (OKT3); and pokeweed mitogen (PWM), Candida sp. (CMA), an extract of T. rubrum, and the main fungal epitope TriR2 (T). We also evaluated interleukin (IL)-4, IL-10, IL-12 and IFN-γ after stimulation by PHA, CMA and TriR2. The immunophenotyping showed no differences between patients and controls. The lymphoproliferation test showed significant differences between the groups stimulated by PWM and CMA, as well as against TriR2, being significantly higher for the control group. Conversely, there were similar results for the groups after stimulation by the extract. The cytokines' quantification showed a significant difference between the groups only for IFN-γ stimulated by PHA and TriR2. We can conclude that the fungal extract can stimulate lymphoproliferation by both groups' lymphocytes. However, the response to Tri r2 was more specific. We showed that some patients with extensive dermatophytosis have normal cellular response, recognising both the extract and TriR2.

Abstract
BACKGROUND AIMS Recent studies have shown that the ligation of Toll-like receptor 3 (TLR3) or Dectin-1 on human monocyte-derived dendritic cells (MoDC) elicits their maturation, but with a different outcome on immunomodulation. Therefore the aim of this work was to study the response of MoDC to the combined effect of polyinosinic:polycytydilic acid [Poly (I:C)] and curdlan, selective TLR3 and Dectin-1 agonists, respectively. METHODS Immature MoDC, generated from human monocytes, were treated with Poly (I:C), curdlan or their combination for 2 days. Phenotypic characteristics of MoDC were determined by flow cytometry, and cytokine production was measured by enzyme-linked immunosorbent assay (ELISA) and FlowCytomix, while the stimulatory capability of MoDC was tested using a mixed leukocyte reaction assay. RESULTS The combination of Poly (I:C) and curdlan induced phenotypic maturation of MoDC with the capability to stimulate an alloreactive response. Such treated MoDC up-regulated the production of interleukin (IL)-12, IL-23 and IL-10, compared with the effect of Poly (I:C) alone. Curdlan-treated MoDC stimulated the production of IL-17 by alloreactive CD4 (+) T cells more strongly than Poly (I:C)-treated MoDC. The opposite effect was observed for interferon(IFN)-γ production. When combined, these agonists primed MoDC to increase further the production of IFN-γ by CD4 (+) T cells in co-culture, especially those of naive (CD45RA (+)) phenotype, and IL-17 by memory (CD45RO (+)) CD4 (+) T cells. CONCLUSIONS Ligation of TLR3 and Dectin-1 receptor up-regulates T-helper (Th) 1 and Th17 immune responses compared with single agonists. These findings may have therapeutic implications for the use of MoDC in immunotherapy.

Abstract
Sarcoidosis is an inflammatory disease. Epidemiological and treatment studies suggest that fungi play a part in the pathogenesis. The aim of this work was to study the effect of fungal cell wall agents (FCWA) on the in vitro secretion of cytokines from peripheral blood monocytes from subjects with sarcoidosis and relate the results to fungal exposure at home and clinical findings. Subjects with sarcoidosis (n=22) and controls (n=20) participated. Peripheral blood mononuclear cells were stimulated with soluble or particulate β-glucan (S-glucan, P-glucan), chitin or lipopolysaccharide (LPS), whereafter tumour necrosis factor (TNF)-α, interleukin (IL)-6, IL-10 and IL-12 were measured. The severity of sarcoidosis was determined using a chest X-ray-based score. Serum cytokines (IL-2R, IL-6, IL-10 and IL-12) were determined. To measure domestic fungal exposure, air in the bedrooms was sampled on filters. N-acetylhexosaminidase (NAHA) on the filters was measured as a marker of fungal cell biomass. The induced secretion of cytokines was higher from peripheral blood mononuclear cells (PBMC) from subjects with sarcoidosis. P-glucan was more potent than S-glucan inducing a secretion. Chitin had a small effect. Among subjects with sarcoidosis there was a significant relation between the spontaneous PBMC production of IL-6, IL-10 and IL-12 and the NAHA levels at home. The P-glucan induced secretion of IL-12 was related to the duration of symptoms at the time of diagnosis. Their X-ray scores were related to an increased secretion of cytokines after stimulation with LPS or P-glucan. Subjects with sarcoidosis have a higher reactivity to FCWA in vitro and to home exposure. The influence of FCWA on inflammatory cells and their interference with the inflammatory defense mechanisms in terms of cytokine secretion could be important factors for the development of sarcoidosis.
