[PMID: 38827132 PMCID: PMC11136906 DOI: 10.1007/s42995-023-00199-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 08/26/2023] [Accepted: 10/16/2023] [Indexed: 06/04/2024]
Abstract
The eye, as a specialized visual organ, is directly exposed to the external environment, and, therefore, it faces constant challenges from external pathogenic organisms and toxins. In the ocular mucosa (OM) of mammals, mucosal-associated lymphoid tissues (MALTs) constitute the primary line of defense. However, the immune defense role of the OM remains unknown in aquatic vertebrates. To gain insights into the immune processes within the OM of teleost fish, we developed an infection model of rainbow trout (Oncorhynchus mykiss) OM using a parasite, Ichthyophthirius multifiliis (Ich). Immunofluorescence, qPCR, and H&E staining revealed that Ich successfully infiltrates the OM of rainbow trout, leading to pathological structural changes, as evidenced by A&B staining. Importantly, the qPCR results indicate an up-regulation of immune-related genes following Ich infection in the OM. Moreover, transcriptome analyses were conducted to detect immune responses and impairments in eye function within the OM of rainbow trout with Ich infection. The results of the transcriptome analysis that Ich infection can cause an extensive immune response in the OM, ultimately affecting ocular function. To the best of our knowledge, our findings represent for the first time that the teleost OM could act as an invasion site for parasites and trigger a strong mucosal immune response to parasitic infection.

Abstract
BACKGROUND The visual organ plays a crucial role in sensing environmental information. However, its mucosal surfaces are constantly exposed to selective pressures from aquatic or airborne pathogens and microbial communities. Although few studies have characterized the conjunctival-associated lymphoid tissue (CALT) in the ocular mucosa (OM) of birds and mammals, little is known regarding the evolutionary origins and functions of immune defense and microbiota homeostasis of the OM in the early vertebrates. RESULTS Our study characterized the structure of the OM microbial ecosystem in rainbow trout (Oncorhynchus mykiss) and confirmed for the first time the presence of a diffuse mucosal-associated lymphoid tissue (MALT) in fish OM. Moreover, the microbial communities residing on the ocular mucosal surface contribute to shaping its immune environment. Interestingly, following IHNV infection, we observed robust immune responses, significant tissue damage, and microbial dysbiosis in the trout OM, particularly in the fornix conjunctiva (FC), which is characterized by the increase of pathobionts and a reduction of beneficial taxa in the relative abundance in OM. Critically, we identified a significant correlation between viral-induced immune responses and microbiome homeostasis in the OM, underscoring its key role in mucosal immunity and microbiota homeostasis. CONCLUSIONS Our findings suggest that immune defense and microbiota homeostasis in OM occurred concurrently in early vertebrate species, shedding light on the coevolution between microbiota and mucosal immunity.

Abstract
Background The orbital glands, viz. lacrimal gland, superficial and deep gland of third eyelid (LG, SGT and HG), are important for normal eye functions. These glands have different functions in various animals. The information about the enzyme histochemical nature of prenatal orbital glands in Indian buffalo seems to be unavailable. Therefore, the study was planned on orbital glands of six full term recently died fetuses from animals with dystocia. Methods The frozen sections of all these glands were subjected to standard localization protocols for Alkaline Phosphatase (AKPase), Glucose 6 phosphatase (G-6-Pase), Lactate dehydrogenase (LDH), Succinate dehydrogenase (SDH), Glucose 6 phosphate dehydrogenase (G-6-PD), Nicotinamide Adenine Dinucleotide Hydrogen Diaphorase (NADHD), Nicotinamide Adenine Dinucleotide Phosphate Hydrogen diaphorase (NADPHD), Dihydroxy phenylalanine oxidase (DOPA-O), Tyrosinase, non-specific esterase (NSE) and Carbonic anhydrase (CAse). Results The results revealed a mixed spectrum of reaction for the above enzymes in LG, SGT and HG which ranged from moderate (for LDH in SGT) to intense (for most of the enzymes in all three glands). However, DOPA-O, Tyrosinase and CAse did not show any reaction. From the present study, it can be postulated that the orbital glands of fetus have a high activity of metabolism as it has many developmental and functional activities which were mediated with the higher activity of the enzymes involved.

Abstract
1. The role of the Harderian gland (HG), choanal cleft (CC) and turbinate in terms of IBV M41 viral load compared to the trachea, and immune (innate, cellular and mucosal) responses were studied in 21-day-old commercial broiler chickens.2. After virulent IBV M41 challenge, the antigen concentration detected either by quantitative RT-PCR or immunohistochemistry peaked at 2-3 days post challenge (dpc) in all tissues. Significant increases of lachrymal IBV-specific IgA and IgY levels were found at 4-5 dpc.3. Gene transcription showed a significant up-regulation of TLR3, MDA5, IL-6, IFN-α and IFN-β, where patterns and magnitude fold-change of mRNA transcription were dependent on the gene and tissue type.4. The results demonstrated active IBV M41 replication in the HG, CC and turbinate, comparable to levels of replication found in the trachea. The data on immune related genes in head-associated tissues provides further understanding on the immunobiology of IBV and offers opportunities to identify their use as quantitative biomarkers in pathogenicity and vaccination-challenge studies.

Abstract
INTRODUCTION Mucosal vaccines have several advantages over parenteral vaccines. They induce both systemic and mucosal antigen-specific immune responses, allow easy administration, and bypass the need for trained medical personnel. AREAS COVERED Eye mucosa is a novel route of mucosal vaccine administration. Eyedrop vaccination induces systemic and mucosal immune responses similar to other forms of mucosal vaccines such as oral and intranasal vaccines. EXPERT OPINION Eyedrop vaccines are free of serious adverse side effects like the infiltration of CNS by pathogens. Studies over the years have shown promising results for eye drop vaccines against infectious agents like the influenza virus, Salmonella typhi, and Escherichia coli in animal models. Such efficacy and safety of eyedrop vaccination enable the application of eyedrop vaccines against other infectious diseases as well as chronic diseases. In this review of published literature, we examine the mechanism, efficacy, and safety of eyedrop vaccines and contemplate their role in times of a pandemic.

Abstract
Purpose To assess the presence of anti-SARS-CoV-2 IgA in the conjunctival secretions of confirmed COVID-19 patients by nasopharyngeal swabs and correlate its presence with the severity of the disease, patient's age, sex and ocular symptoms. Methods This study included 44 positive COVID-19 patients confirmed with nasopharyngeal swabs during the period 17-28 February 2021 at Sohag Tropical Medicine Hospital. Tears and conjunctival secretions were examined for the presence of anti-SARS-CoV-2 IgA. Results While non-reactive results are strongly correlated to low titre and vice versa, severity showed significant correlation with neither IgA reactivity nor titre. Meanwhile, IgA reactivity did not show significant correlation with either age or sex. The reactivity and IgA titre are correlated with ocular symptoms. Conclusion The anti-SARS-CoV-2 IgA could be found in ocular secretions in SARS-CoV-2 patients. There is no correlation with age or sex or severity of the disease; however, they are correlated with ocular symptoms.

Abstract
The chicken major histocompatibility complex (MHC) B locus has been linked to resistance to infectious diseases. We have previously provided evidence that the MHC congenic chicken lines 331/B2 and 335/B19 differ in susceptibility to infectious bronchitis virus (IBV) strains M41 and ArkDPI in in vivo challenge experiments. Innate immune responses can be difficult to measure in vivo because they are nonspecific and can be triggered by environmental factors. In an attempt to address this issue, we used tracheal organ cultures derived from 331/B2 and 335/B19 birds to study local cytokine production after in vitro challenge with IBV M41. Interferon (IFN)-β, interleukin (IL)-1β, IL-6, and IL-10 gene expression and production were assessed. Tracheal organ cultures derived from 335/B19 birds presented an increased inflammatory response compared to 331/B2. However, it was not possible to discriminate between cytokine responses in IBV-infected and phosphate-buffered saline-treated tracheal organ cultures. Because tracheal processing entails physical damage to the trachea, it is possible that the tracheal organ cultures presented high levels of inflammation regardless of the IBV challenge. To demonstrate the effects of IBV on innate immune responses in the MHC congenic chicken lines, we performed an additional in vivo experiment that focused on cytokine gene expression and production in tracheas up to 60 hr after a challenge with IBV M41. Our results corroborate previous in vivo observations that suggest that detrimental local inflammatory responses in 335/B19 birds might be associated with their susceptibility to IBV and that inflammation does not necessarily lead to the assembly of an appropriate adaptive immune response. This work provides further insight into the increased susceptibility of 335/B19 birds to infectious bronchitis.

Abstract
The accessory organs of the eye represent part of the protective system of the eyeball. In the present study, an examination of the accessory organs of the eye of three species of captive ruminants was performed using light microscopy. In the okapi, the superficial gland of the third eyelid and lacrimal gland were complex branched multilobar tubular glands formed by mucous units with tubular secretory portions and no plasma cells. The deep gland of the third eyelid was absent in the okapi and present in both the Père David's deer and the Philippine mouse-deer. In the Philippine mouse-deer, the deep gland had a very thick connective capsule and thick interlobar septae. It contained fewer lobes forming the gland parenchyma compared to Père David's deer and other ruminants. Organized lymphoid follicles were present within the upper and lower eyelids only in the okapi and Père David's deer, while diffuse lymphocytes were observed in the Philippine mouse-deer. The orbital glands in the Père David's deer had a multilobar tubuloacinar structure with numerous plasma cells and a mucoserous character. In contrast to the Philippine mouse-deer, these glands had a serous character. The presence of several macroscopic and microscopic structural differences of the examined accessory organs of the eye in the three captive ruminant species may be understood within an ecological context and may be associated with different habitat-specific environmental conditions.

Abstract
Vaccines are one of the greatest medical interventions of all time and have been successful in controlling and eliminating a myriad of diseases over the past two centuries. Among several vaccination strategies, mucosal vaccines have wide clinical applications and attract considerable interest in research, showing potential as innovative and novel therapeutics. In mucosal vaccination, targeting (microfold) M cells is a frontline prerequisite for inducing effective antigen-specific immunostimulatory effects. In this review, we primarily focus on materials engineered for use as vaccine delivery platforms to target M cells. We also describe potential M cell targeting areas, methods to overcome current challenges and limitations of the field. Furthermore, we present the potential of biomaterials engineering as well as various natural and synthetic delivery technologies to overcome the challenges of M cell targeting, all of which are absent in current literature. Finally, we briefly discuss manufacturing and regulatory processes to bring a robust perspective on the feasibility and potential of this next-generation vaccine technology.

Abstract
Until recently, the ocular surface is thought by many to be sterile and devoid of living microbes. It is now becoming clear that this may not be the case. Recent and sophisticated PCR analyses have shown that microbial DNA-based "signatures" are present within various ethnic, geographic, and contact lens wearing communities. Furthermore, using a mouse model of ocular surface disease, we have shown that the microbe, Corynebacterium mastitidis (C. mast), can stably colonize the ocular mucosa and that a causal relationship exists between ocular C. mast colonization and beneficial local immunity. While this constitutes proof-of-concept that a bona fide ocular microbiome that tunes immunity can exist at the ocular surface, there remain numerous unanswered questions to be addressed before microbiome-modulating therapies may be successfully developed. Here, the authors will briefly outline what is currently known about the local ocular microbiome as well as microbiomes associated with other sites, and how those sites may play a role in ocular surface immunity. Understanding how commensal microbes affect the ocular surface immune homeostasis has the potential revolutionize how we think about treating ocular surface disease.

Abstract
The mucosal immune system is a compartmentalized part of the immune system that provides local immunity in the mucosa of the respiratory, gastrointestinal, and digestive tracts. It possesses secondary lymphoid tissues, which contain immune cells, such as T, B, and dendritic cells. Once the cells of the mucosal immune system are stimulated by luminal antigens, including microorganisms, they infiltrate into diffuse areas of mucosal tissues (e.g., respiratory mucosa and lamina propria of intestinal villi) and exhibit immune effector functions. Inducing the antigen-specific immune responses in mucosal tissues by mucosal vaccination would be an ideal strategy for not only humans, but also mammals and birds, to protect against infectious diseases occurring in mucosal tissues (e.g., pneumonia and diarrhea). Infectious diseases cause huge economic losses in agriculture, such as livestock and poultry industries. Since most infectious diseases occur in mucosal tissues, vaccines that are capable of inducing immune responses in mucosal tissues are in high need. In this review, we discuss the current understanding of mucosal immunity in mammals and birds, and recent progress in the development of mucosal vaccines.

Abstract
Genetic resistance or susceptibility to infectious diseases has been largely associated with the avian major histocompatibility complex (MHC) genes. Our goal was to determine resistance and susceptibility of MHC B haplotype in congenic and inbred chicken lines in order to establish a resistant-susceptible model. Eight congenic lines (253/B18, 254/B15, 330/B21, 312/B24, 331/B2, 335/B19, 336/B21, and 342/BO), two inbred lines (003/B17 and 077/B19), and three commercial lines (white leghorn, brown layers, and broilers) were used in two experiments. We analyzed and compared immunologic responses and the effect of challenge by measuring viral load, IgG and IgA humoral responses, histopathology and histomorphometry, clinical signs, and immune cell populations in the different MHC B haplotype lines. We found that respiratory signs, tracheal deciliation and inflammation, airsacculitis, viral shedding in tears, and local humoral responses were good parameters to determine resistance or susceptibility. Based on these results, we identified 331/B2 as the most resistant and 335/B19 as the most susceptible congenic chicken lines. These two lines will be used as an animal model in subsequent experiments to understand the mechanisms by which the immune system in chickens generates resistance to infectious bronchitis virus.

Abstract
Infectious laryngotracheitis virus (ILTV) has a high proclivity to replicate in the larynx and trachea of chickens causing severe lesions. There is a lack of knowledge on the ability of ILTV to replicate in other respiratory associated tissues apart from in the trachea. The objective of this study was to investigate how tissues that first encounter the virus dictate further sites of viral replication during the lytic stage of infection. Replication patterns of the pathogenic strain 63140 and the chicken embryo origin (CEO) vaccine in the conjunctiva, the Harderian gland, nasal cavity and trachea were evaluated after ocular, oral, intranasal or intratracheal inoculation of specific pathogen-free chickens. Viral replication was assessed by detection of microscopic cytolytic lesions, detection of viral antigen and viral genome load. The route of viral entry greatly influenced virus replication of both strain 63140 and CEO vaccine in the conjunctiva and trachea, while replication in the nasal cavity was not affected. In the Harderian gland, independently of the route of viral entry, microscopic lesions characteristic of lytic replication were absent, whereas viral antigen and viral genomes for either virus were detected, suggesting that the Harderian gland may be a key site of antigen uptake. Findings from this study suggest that interactions of the virus with the epithelial-lymphoid tissues of the nasal cavity, conjunctiva and the Harderian gland dictate patterns of ILTV lytic replication.

Abstract
Normal structure of the accessory organs of the eye is essential for normal eye physiology. Among the most important accessory organs of the eye are the eyelids, the conjunctiva-associated lymphoid tissue (CALT) and the lacrimal gland (LG). The aim of this study was to demonstrate the histological structure of the eyelids and LG by histochemical and ultrastructural analysis. The study was performed on 13 adult female Bilgorajska geese. Eyelid samples were stained with the Alcian blue (AB pH 2.5) and periodic acid-Schiff (PAS) methods. Staining methods used for LG were AB pH 2.5, aldehyde fuchsin (AF), PAS and Hale's dialysed iron (HDI). Within the connective tissue of the eyelids, well-developed, diffuse, CALT follicles were observed, mostly under the conjunctival epithelium. Numerous lymphocytes were present within loose connective tissue. Staining of the eyelids with the PAS method demonstrated the presence of goblet cells of a mucous nature, and AB pH 2.5 staining indicated the presence of sulfated acid mucopolysaccharides. PAS staining of LG revealed the presence of secretory cells containing weakly PAS-positive granules. All epithelial cells of the corpus glandulae and the duct systems reacted positively to AB pH 2.5. HDI staining detected the presence of carboxylated acid mucopolysaccharides. Transmission electron microscopy investigations revealed two types of secretory epithelial cells in LG. Both types of LG cells contained drop-like secretory vesicles of different sizes with low or high electron density in cytoplasm, as well as small and large lipid vacuoles, and numerous small primary lysosomes.

Abstract
Humoral immunity is important for controlling viral diseases of poultry, but recent studies have indicated that cytotoxic T cells also play an important role in the immune response to infectious bronchitis virus (IBV). To better understand the cell mediated immune responses to IBV in the mucosal and systemic immune compartments chickens were ocularly vaccinated with IBV. This induced a lymphocyte expansion in head-associated lymphoid tissues (HALT) and to a lesser extent in the spleen, followed by a rapid decline, probably due to homing of lymphocytes out of these organs and contraction of the lymphocyte population. This interpretation was supported by observations that changes in mononuclear cells were mirrored by that in CD3(+)CD44(+) T cell abundance, which presumably represent T effector cells. Increased interferon gamma (IFN-γ) expression was observed in the mucosal immune compartment, i.e., HALT, after primary vaccination, but shifted to the systemic immune compartment after boosting. In contrast, the expression of cytotoxicity-associated genes, i.e., granzyme A (GZMA) and perforin mRNA, remained associated with the HALT after boosting. Thus, an Ark-type IBV ocular vaccine induces a central memory IFN-γ response in the spleen while the cytotoxic effector memory response, as measured by GZMA and perforin mRNA expression, remains associated with CALT after boosting.

Intraocular vaccination with an inactivated highly pathogenic avian influenza virus induces protective antibody responses in chickens. Vet Immunol Immunopathol 2012; 151:83-9.

Abstract
Because it is expected to induce cross-reactive serum and mucosal antibody responses, mucosal vaccination against highly pathogenic avian influenza (HPAI) is potentially superior to conventional parenteral vaccination. Here, we tested whether intraocular vaccination with an inactivated AI virus induced protective antibody responses in chickens. Chickens were inoculated intraocularly twice with 10(4) hemagglutination units of an inactivated H5N1 HPAI virus. Four weeks after the second vaccination, the chickens were challenged with a lethal dose of the homologous H5N1 HPAI virus. Results showed that most of the vaccinated chickens mounted positive antibody responses. The median serum hemagglutination inhibition titer was 1:80. Addition of CpG oligodeoxynucleotide 2006 or cholera toxin to the vaccine did not enhance serum antibody titers. Cross-reactive anti-hemagglutinin IgG, but not IgA, was detected in oropharyngeal secretions. In accordance with these antibody results, most vaccinated chickens survived a lethal challenge with the H5N1 HPAI virus and did not shed the challenge virus in respiratory or digestive tract secretions. Our results show that intraocular vaccination with an inactivated AI virus induces not only systemic but also mucosal antibody responses and confers protection against HPAI in chickens.
