The Interactions between Nanoparticles and the Innate Immune System from a Nanotechnologist Perspective. NANOMATERIALS 2021; 11:nano11112991. [PMID: 34835755 PMCID: PMC8621168 DOI: 10.3390/nano11112991] [Citation(s) in RCA: 28] [Impact Index Per Article: 9.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/16/2021] [Revised: 11/02/2021] [Accepted: 11/03/2021] [Indexed: 12/24/2022]
Abstract
The immune system contributes to maintaining the body’s functional integrity through its two main functions: recognizing and destroying foreign external agents (invading microorganisms) and identifying and eliminating senescent cells and damaged or abnormal endogenous entities (such as cellular debris or misfolded/degraded proteins). Accordingly, the immune system can detect molecular and cellular structures with a spatial resolution of a few nm, which allows for detecting molecular patterns expressed in a great variety of pathogens, including viral and bacterial proteins and bacterial nucleic acid sequences. Such patterns are also expressed in abnormal cells. In this context, it is expected that nanostructured materials in the size range of proteins, protein aggregates, and viruses with different molecular coatings can engage in a sophisticated interaction with the immune system. Nanoparticles can be recognized or passed undetected by the immune system. Once detected, they can be tolerated or induce defensive (inflammatory) or anti-inflammatory responses. This paper describes the different modes of interaction between nanoparticles, especially inorganic nanoparticles, and the immune system, especially the innate immune system. This perspective should help to propose a set of selection rules for nanosafety-by-design and medical nanoparticle design.

Abstract
Paediatric sarcoidosis is an extremely rare disease characterized by a granulomatous inflammation. The estimated incidence is 0.6-1.02/100,000 children, but in the absence of international registers, the disease is probably under-reported. Its pathophysiologic basis is not clearly understood but the current hypothesis is a combination of a genetic predisposition and an environmental exposure that could be either organic or mineral. Contrary to adult forms of the disease, general symptoms are often at the forefront at diagnosis. In its most frequent form, paediatric sarcoidosis is a multi-organ disorder affecting preferentially the lungs, the lymphatic system and the liver, but all organs can be affected. This review aims to provide an overview of current knowledge on sarcoidosis in children, providing a summary of the data available from cohort studies on the presentation, the management and the evolution of the disease in this specific population.

Abstract
Inhalation of mineral dust was suggested to contribute to sarcoidosis. We compared the mineral exposome of 20 sarcoidosis and 20 matched healthy subjects. Bronchoalveolar lavage (BAL) samples were treated by digestion-filtration and analyzed by transmission electron microscopy. The chemical composition of inorganic particles was determined by energy-dispersive X-ray (EDX) spectroscopy. Dust exposure was also assessed by a specific questionnaire. Eight sarcoidosis patients and five healthy volunteers had a high dust load in their BAL. No significant difference was observed between the overall inorganic particle load of each group while a significant higher load for steel was observed in sarcoidosis patients (p=0.029). Moreover, the building activity sub-score was significantly higher in sarcoidosis patients (p=0.018). These results suggest that building work could be a risk factor for sarcoidosis which could be considered at least in some cases as a granulomatosis caused by airborne inorganic dust. The questionnaire should be validated in larger studies. (Sarcoidosis Vasc Diffuse Lung Dis 2018; 35: 327-332)

Abstract
In April 2016, the German Society of Hygiene, Environmental Medicine and Preventative Medicine (Gesellschaft für Hygiene, Umweltmedizin und Präventivmedizin (GHUP)) together with other scientific medical societies, German and Austrian medical societies, physician unions and experts has provided an AWMF (Association of the Scientific Medical Societies) guideline 'Medical diagnostics for indoor mold exposure'. This guideline shall help physicians to advise and treat patients exposed indoors to mold. Indoor mold growth is a potential health risk, even without a quantitative and/or causal association between the occurrence of individual mold species and health effects. Apart from the allergic bronchopulmonary aspergillosis (ABPA) and the mycoses caused by mold, there is only sufficient evidence for the following associations between moisture/mold damages and different health effects: Allergic respiratory diseases, asthma (manifestation, progression, exacerbation), allergic rhinitis, exogenous allergic alveolitis and respiratory tract infections/bronchitis. In comparison to other environmental allergens, the sensitizing potential of molds is estimated to be low. Recent studies show a prevalence of sensitization of 3-10% in the total population of Europe. The evidence for associations to mucous membrane irritation and atopic eczema (manifestation, progression, exacerbation) is classified as limited or suspected. Inadequate or insufficient evidence for an association is given for COPD, acute idiopathic pulmonary hemorrhage in children, rheumatism/arthritis, sarcoidosis, and cancer. The risk of infections from indoor molds is low for healthy individuals. Only molds that are capable to form toxins can cause intoxications. The environmental and growth conditions and especially the substrate determine whether toxin formation occurs, but indoor air concentrations are always very low. In the case of indoor moisture/mold damages, everyone can be affected by odor effects and/or impairment of well-being. Predisposing factors for odor effects can be given by genetic and hormonal influences, imprinting, context and adaptation effects. Predisposing factors for impairment of well-being are environmental concerns, anxieties, conditioning and attributions as well as a variety of diseases. Risk groups that must be protected are patients with immunosuppression and with mucoviscidosis (cystic fibrosis) with regard to infections and individuals with mucoviscidosis and asthma with regard to allergies. If an association between mold exposure and health effects is suspected, the medical diagnosis includes medical history, physical examination, conventional allergy diagnosis, and if indicated, provocation tests. For the treatment of mold infections, it is referred to the AWMF guidelines for diagnosis and treatment of invasive Aspergillus infections. Regarding mycotoxins, there are currently no validated test methods that could be used in clinical diagnostics. From the perspective of preventive medicine, it is important that mold damages cannot be tolerated in indoor environments.

Abstract
Sarcoidosis is a debilitating, inflammatory, multiorgan, granulomatous disease of unknown cause, commonly affecting the lung. In contrast to other chronic lung diseases such as interstitial pulmonary fibrosis or pulmonary arterial hypertension, there is so far no widely accepted or implemented animal model for this disease. This has hampered our insights into the etiology of sarcoidosis, the mechanisms of its pathogenesis, the identification of new biomarkers and diagnostic tools and, last not least, the development and implementation of novel treatment strategies. Over past years, however, a number of new animal models have been described that may provide useful tools to fill these critical knowledge gaps. In this review, we therefore outline the present status quo for animal models of sarcoidosis, comparing their pros and cons with respect to their ability to mimic the etiological, clinical and histological hallmarks of human disease and discuss their applicability for future research. Overall, the recent surge in animal models has markedly expanded our options for translational research; however, given the relative early stage of most animal models for sarcoidosis, appropriate replication of etiological and histological features of clinical disease, reproducibility and usefulness in terms of identification of new therapeutic targets and biomarkers, and testing of new treatments should be prioritized when considering the refinement of existing or the development of new models.

Abstract
Sarcoidosis is a multisystem inflammatory disease, the aetiology of which has still to be resolved. The proposed mechanism is that a susceptible genotype is exposed to one or more potential antigens. A sustained inflammatory response follows, which ultimately results in pathognomonic granuloma formation. Various clinical phenotypes exist with specific genetic associations influencing disease susceptibility, protection, and clinical progression. Occupational and environmental factors, including microbial elements, may then effect the development of this disease. Sarcoidosis is a heterogeneous disease, showing geographic and racial variation in clinical presentation. It demonstrates a familial tendency and clear genotype associations. Additionally, it appears to cluster within closely associated populations (eg, work colleagues) and appears to be related to selected occupations and environmental exposures. Frequently occult, but occasionally fatal, this disease has a very variable prognosis. It is also unusual in having no specific biomarker. The epidemiology and multiple factors that appear to influence the aetiology of sarcoidosis illustrate why this disease state is frequently described as a clinical enigma.

Abstract
Macrophages play a central role in immune and tissue responses of granulomatous lung diseases induced by pathogens and foreign bodies. Circulating monocytes are generally viewed as central precursors of these tissue effector macrophages. Here, we provide evidence that granulomas derive from alveolar macrophages serving as a local reservoir for the expansion of activated phagocytic macrophages. By exploring lung granulomatous responses to silica particles in IL-1-deficient mice, we found that the absence of IL-1α, but not IL-1β, was associated with reduced CD11b(high) phagocytic macrophage accumulation and fewer granulomas. This defect was associated with impaired alveolar clearance and resulted in the development of pulmonary alveolar proteinosis (PAP). Reconstitution of IL-1α(-/-) mice with recombinant IL-1α restored lung clearance functions and the pulmonary accumulation of CD11b(high) phagocytic macrophages. Mechanistically, IL-1α induced the proliferation of CD11b(low) alveolar macrophages and differentiated these cells into CD11b(high) macrophages which perform critical phagocytic functions and organize granuloma. We newly discovered here that IL-1α triggers lung responses requiring macrophage proliferation and maturation from tissue-resident macrophages.

Abstract
Sarcoidosis is a multisystem granulomatous disorder invariably affecting the lungs. It is a disease with noteworthy variations in clinical manifestation and disease outcome and has been described as an “immune paradox” with peripheral anergy despite exaggerated inflammation at disease sites. Despite extensive research, sarcoidosis remains a disease with undetermined aetiology. Current evidence supports the notion that the immune response in sarcoidosis is driven by a putative antigen in a genetically susceptible individual. Unfortunately, there currently exists no reliable biomarker to delineate the disease severity and prognosis. As such, the diagnosis of sarcoidosis remains a vexing clinical challenge. In this review, we outline the immunological features of sarcoidosis, discuss the evidence for and against various candidate etiological agents (infective and noninfective), describe the exhaled breath condensate, a novel method of identifying immunological biomarkers, and suggest other possible immunological biomarkers to better characterise the immunopathogenesis of sarcoidosis.

Abstract
CONTEXT Sarcoidosis is a granulomatous disease of unclear etiology. It is not commonly fatal, but when sarcoidosis is fatal, it is most often from cardiac involvement and when sarcoidosis involves the heart, it frequently causes death. The disease presents diagnostic challenges both clinically and histologically. OBJECTIVES To review the histology of cardiac sarcoidosis and the histologic differential diagnosis of cardiac granulomatous disease and to review the epidemiology and gross pathology of cardiac sarcoid as well as discuss current controversies, clinical diagnostic criteria, and proposed mechanisms of pathogenesis. DATA SOURCES We reviewed the literature searchable on PubMed as well as selected older studies revealed by our review of the recent literature. Photographs were taken from cases on file at the University of Pittsburgh Medical Center (Pittsburgh, Pennsylvania) and Columbia University Medical Center (New York, New York). CONCLUSIONS Sarcoidosis is a focal or disseminated granulomatous disease that likely represents the final common pathway of various pathogenic insults in a genetically susceptible host. The type of insult may influence the specific sarcoid phenotype. Controversy still abounds, but many areas of investigation around sarcoidosis are yielding exciting discoveries and bringing us closer to a richer understanding of this puzzling disease.

Abstract
A 52-year-old woman presented with headaches, difficulty with word finding and left eye blindness. MRI showed enhancing frontal dural-based masses suggestive of meningiomatosis. Biopsy and debulking revealed necrotising granulomas, without discernible micro-organisms or neoplasia; a thorough clinical work-up was negative for infection and vasculitis. A CT scan showed mild bilateral hilar lymphadenopathy, a tiny pulmonary nodule and cirrhotic liver. Her subsequent alteration of mental status was attributed to hepatic encephalopathy based upon elevated aminotransferase and ammonia levels, biopsy evidence of hepatoportal sclerosis with rare granulomas and response to lactulose. A diagnosis of neurosarcoidosis of the necrotising sarcoid granulomatosis variant (NS-NSG) with atypical systemic involvement was made. This is the fifth case report of NS-NSG clinically mimicking a neoplasm and histologically mimicking a mycobacterial infection. NS-NSG can have an atypical clinical picture including intracranial masses; a thorough work-up to exclude infectious and other non-infectious aetiologies is a prerequisite to its diagnosis.

Abstract
Mannose-Binding Lectin (MBL) is a prognostic marker in pulmonary diseases. Ficolins, sharing many structural and functional similarities with MBL, may also be involved in the pathogenesis of pulmonary diseases. The objectives of the study were to establish whether plasma concentrations of Ficolin-2, -3, and MBL in Danish patients with sarcoidosis and control persons differed and whether they were of prognostic significance. We retrospectively included 46 consecutive patients (26 male, 20 female) and 51 age- and sex-matched healthy control persons (28 male, 23 female). Information about the patients was obtained from their medical records. We measured plasma concentrations of Ficolin-2, -3, and MBL using ELISA. There was a significant difference in the patients' mean Ficolin-3 plasma level (14.9 microg/ml; +/-2SD: 6.7-23.1) compared with the control persons' (21.6 microg/ml; +/-2SD: 12.7-30.5). The difference was 6.7 microg/ml (95% CI: 5.0-8.4 microg/ml; p<0.001). In the patients, Ficolin-3 correlated inversely with the CD4(+)/CD8(+)-ratio (Spearman's Rho=-0.37; p=0.021; n=39). There were no significant differences in plasma concentrations of Ficolin-2 or MBL between the two groups. Ficolin-3 concentrations were lower in plasma from patients with sarcoidosis. This suggests a possible involvement of Ficolin-3 in the complex pathophysiology of sarcoidosis. However, we could not show the applicability of Ficolin plasma level measurement as a marker of disease activity or of prognostic significance in sarcoidosis.

Abstract
Clinicians and pathologists do their work, of course, in quite different ways. Because both groups are trained as physicians, however, this training commonality makes all involved seem basically to be on the same "medical team." There are, nevertheless, some fundamental differences between the 2 groups that can on occasion cause significant difficulties in mutual understanding; there are reasons to believe that such differences are becoming more pronounced. Although the differences in viewpoints are often subtle and, therefore, seemingly not very important, these differences have very profound causes and can be profound in their effects. This narrative examines the underlying broad historical-sociological-philosophical bases for these differences with the aim of illuminating their importance to medicine and their prospective importance to pathology in particular.
