“…Similarly, it was shown that P. gingivalis infection elicited P. gingivalis-specific IgA responses in saliva as well as IgG and IgA in serum (47). Moreover, experiments with animal models have also shown that salivary IgA specific to Candida albicans has an inhibitory effect on the adherence of C. albicans yeast cells to oral surfaces (24,25). Overall, our results indicate that mucosal Ig (sIgT) play a key role in the BM immunity against bacterial pathogens of fish.…”

“…However, after bacterial infection, the local responses of mucosal B-cells and specific responses mediated by IgT in teleost BM are thus far unknown. Interestingly, bacteria-specific IgA antibodies have been detected in saliva after bacterial infection in mammalians (24,25). Since teleost IgT and mammalian IgA have evolved through a process of convergent evolution, we hypothesize that sIgT plays a key role in fish buccal immune responses to bacterial infection.…”

The buccal mucosa (BM) of vertebrates is a critical mucosal barrier constantly exposed to rich and diverse pathogens from air, water, and food. While mammals are known to contain a mucosal associated lymphoid tissue (MALT) in the buccal cavity which induces B-cells and immunoglobulins (Igs) responses against bacterial pathogens, however, very little is known about the evolutionary roles of buccal MALT in immune defense. Here we developed a bath infection model that rainbow trout experimentally exposed to Flavobacterium columnare (F. columnare), which is well known as a mucosal pathogen. Using this model, we provided the first evidence for the process of bacterial invasion in the fish BM. Moreover, strong pathogen-specific IgT responses and accumulation of IgT + B-cells were induced in the buccal mucus and BM of infected trout with F. columnare. In contrast, specific IgM responses were for the most part detected in the fish serum. More specifically, we showed that the local proliferation of IgT + B-cells and production of pathogen-specific IgT within the BM upon bacterial infection. Overall, our findings represent the first demonstration that IgT is the main Ig isotype specialized for buccal immune responses against bacterial infection in a non-tetrapod species.

“…2 With time, such exposure, alone or associated with underlying disorders, is thought to generate physiological and pathological changes, 3 which may lead to temporomandibular joint dysfunction (TMD) of varying complexity and magnitude. 4 5 6 7 The most common symptoms reported by patients with TMD include pain, deviations or restrictions in the range of motion, presence of clicking, crackling, or popping sounds, 8 and otologic symptoms such as tinnitus, 9 defined as a phantom sound in the absence of an external source. 10…”

Introduction The prevalence of tinnitus is higher in individuals with temporomandibular joint disorder (TMD) than in the general population. Magnetic resonance imaging (MRI) of the temporomandibular joint (TMJ) is the method of choice for investigation, and it has been hypothesized that specific MRI findings might be observed in TMD with comorbid tinnitus. Objective To comparatively describe MRI findings in patients with TMD with and without tinnitus, identifying the most common TMJ alterations and determining whether a correlation exists between severity of TMD and tinnitus. Methods A cross-sectional study of 53 adult patients with bilateral or unilateral TMD (30 with and 23 without tinnitus). The association between tinnitus and morphological aspects of TMD (changes in condylar morphology, articular eminence morphology, and disc morphology), disc displacement (with/without reduction), condylar translation, and intra-articular effusion was analyzed on MRI images. Results The mean patient age was 46.12 ± 16.1 years. Disc displacement was the most common finding in both groups (24 patients with tinnitus versus 15 without; p = 0.043). Only the frequency of disc displacement with reduction was significantly different between groups. Conclusion Additional imaging techniques should be explored to detect specific aspects of the relationship between tinnitus and TMD.

“…Most of the individuals develop immunological defense, which avoid the growth and progression of Candida. However, in some situations as antibiotic therapy, use of prosthesis and orthodontic devices and immunosuppression, Candida may grow and cause different superficial or systemic diseases, especially in the oral and vaginal mucosae [8][9][10].…”
