Abstract
The differentiation of neural crest (NC) cells into various cell lineages contributes to the formation of many organs, including the thymus. In this study, we explored the role of NC cells in thymic T cell development. In double-transgenic mice expressing NC-specific Cre and the Cre-driven diphtheria toxin receptor, plasma noradrenaline and adrenaline levels were significantly reduced, as were thymic T cell progenitors, when NC-derived cells were ablated with short-term administration of diphtheria toxin. Additionally, yellow fluorescent protein+ NC-derived mesenchymal cells, perivascular cells, and tyrosine hydroxylase+ sympathetic nerves in the thymus significantly decreased. Furthermore, i.p. administration of 6-hydroxydopamine, a known neurotoxin for noradrenergic neurons, resulted in a significant decrease in thymic tyrosine hydroxylase+ nerves, a phenotype similar to that of depleted NC-derived cells, whereas administration of a noradrenaline precursor for ablating NC-derived cells or sympathetic nerves rarely rescued this phenotype. To clarify the role of NC-derived cells in the adult thymus, we transplanted thymus into the renal capsules of wild-type mice and observed abnormal T cell development in lethally irradiated thymus with ablation of NC-derived cells or sympathetic nerves, suggesting that NC-derived cells inside and outside of the thymus contribute to T cell development. In particular, the ablation of NC-derived mesenchymal cells in the thymus decreases the number of thymocytes and T cell progenitors. Overall, ablation of NC-derived cells, including sympathetic nerves, in the thymus leads to abnormal T cell development in part by lowering plasma noradrenalin levels. This study reveals that NC-derived cells including mesenchymal cells and sympathetic nerves within thymus regulate T cell development.

Abstract
The central nervous system (CNS) influences the immune system generally by regulating the systemic concentration of humoral substances (e.g., cortisol and epinephrine), whereas the peripheral nervous system (PNS) communicates specifically with the immune system according to local interactions/connections. An imbalance between the components of the PNS might contribute to pathogenesis and the further development of certain diseases. In this review, we have explored the "thread" (hardwiring) of the connections between the immune system (e.g., primary/secondary/tertiary lymphoid tissues/organs) and PNS (e.g., sensory, sympathetic, parasympathetic, and enteric nervous systems (ENS)) in health and disease in vitro and in vivo. Neuroimmune cell units provide an anatomical and physiological basis for bidirectional crosstalk between the PNS and the immune system in peripheral tissues, including lymphoid tissues and organs. These neuroimmune interactions/modulation studies might greatly contribute to a better understanding of the mechanisms through which the PNS possibly affects cellular and humoral-mediated immune responses or vice versa in health and diseases. Physical, chemical, pharmacological, and other manipulations of these neuroimmune interactions should bring about the development of practical therapeutic applications for certain neurological, neuroimmunological, infectious, inflammatory, and immunological disorders/diseases.

Abstract
Transient Receptor Potential Ankyrin 1 (TRPA1) has been reported to influence neuroinflammation and lymphocyte function. We analysed the immune phenotype and activation characteristics of TRPA1-deficient mice (knockout—KO) generated by targeted deletion of the pore-loop domain of the ion channel. We compared TRPA1 mRNA and protein expression in monocyte and lymphocyte subpopulations isolated from primary and secondary lymphatic organs of wild type (WT) and KO mice. qRT-PCR and flow cytometric studies indicated a higher level of TRPA1 in monocytes than in lymphocytes, but both were orders of magnitude lower than in sensory neurons. We found lower CD4+/CD8+ thymocyte ratios, diminished CD4/CD8 rates, and B cell numbers in the KO mice. Early activation marker CD69 was lower in CD4+ T cells of KO, while the level of CD8+/CD25+ cells was higher. In vitro TcR-mediated activation did not result in significant differences in CD69 level between WT and KO splenocytes, but lower cytokine (IL-1β, IL-6, TNF-α, IL-17A, IL-22, and RANTES) secretion was observed in KO splenocytes. Basal intracellular Ca2+ level and TcR-induced Ca2+ signal in T lymphocytes did not differ significantly, but interestingly, imiquimod-induced Ca2+ level in KO thymocytes was higher. Our results support the role of TRPA1 in the regulation of activation, cytokine production, and T and B lymphocytes composition in mice.

GFAP and desmin expression in lymphatic tissues leads to difficulties in distinguishing between glial and stromal cells. Sci Rep 2021; 11:13322.

Abstract
Recently, we found many immune cells including antigen presenting cells neurally hard wired in the T-cell zone of most lymphoid organs like amongst others, lymph nodes in rats, mice and humans. Single immune cells were reached by single neurites and enclosed with a dense neural meshwork. As it is well known that axons are always accompanied by glial cells, we were able to identify Schwann cells in the hilum, medullary and capsule region, like expected. Unexpected was the result, that we found oligodendrocyte-like cells in these regions, myelinating more than one axon. Likewise important was the finding, that one of the standard glial markers used, a polyclonal GFAP antibody equally bound to desmin and therefore marked nearly all stromal cells in cortical, paracortical and medullary cord regions. More detailed analysis showed that these results also appeared in many other non-lymphoid organs. Therefore, polyclonal GFAP antibodies are only conditionally usable for immunohistochemical analysis in peripheral tissues outside the central nervous system. It remains to be elucidated, if the binding of the GFAP antibody to desmin has its reason in a special desmin variant that can give stromal cells glial character.

Abstract
ZusammenfassungÜber einen möglichen Zusammenhang zwischen psychologischem
Stress, Immunsystem und Autoimmunität wird schon lange debattiert.
Erkenntnisse aus der Grundlagen- und epidemiologischen Forschung, die das
Verständnis für diesen komplexen Zusammenhang
erhöhen werden in dieser kurzen Übersicht zusammengestellt.
Zunächst werden bekannte anatomisch-physiologische Grundlagen
für einen Zusammenhang zwischen psychologischem Stress und
Immunsystem dargestellt. Es wird beschrieben, dass die Interaktion zwischen
Gehirn über autonomes Nervensystem und Hormonsystem bis zur
Immunzelle mit entsprechenden Rezeptoren für Neurotransmitter und
Hormone mittlerweile bis auf die molekulare Ebene gut beschrieben ist. Im
Rahmen der akuten Stressreaktion treten charakteristische
Veränderungen im Immunsystem auf, die ebenfalls gut dokumentiert
sind. In einem zweiten Teil wird dann beschrieben welche
Veränderungen im Rahmen einer chronischen Stressbelastung am
Immunsystem auftreten können und zuletzt wird diskutiert inwiefern
diese Veränderungen auch für pathophysiologische
Zustände des Immunsystems, z. B. im Rahmen von
Autoimmunerkrankungen, relevant sein könnten. Zusammenfassend
führt akuter Stress, im Sinne der optimalen Vorbereitung einer
fight&flight Situation, zu einer Steigerung der Immunfunktion
v. a. der humoralen Immunität, wohingegen die Auswirkungen
von chronischem Stress weniger klar definiert sind und es eher zu einer
Immundysregulation mit verminderter basaler Immunfunktion, v. a. der
zytotoxischen Funktion aber einer gesteigerten Reaktion nach Aktivierung,
v. a. im angeborenen Immunschenkel kommt. Epidemiologische Daten
belegen gut, dass chronischer Stress zu einer erhöhten
Suzeptibilität für Autoimmunerkrankungen führt.
Erste klinische Anwendungen, wie beispielsweise die gezielte neuronale
Stimulation des N. vagus sind in Erprobung, für einen breiteren
klinischen Einsatz sollten aber die biologischen Netzwerkstrukturen noch
besser verstanden werden, um die besten Angriffspunkte zu finden.

Abstract
The stromal microenvironment in the thymus is essential for generating a functional T cell repertoire. Thymic epithelial cells (TECs) are numerically and phenotypically one of the most prominent stromal cell types in the thymus, and have been recognized as one of most unusual cell types in the body by virtue of their unique functions in the course of the positive and negative selection of developing T cells. In addition to TECs, there are other stromal cell types of mesenchymal origin, such as fibroblasts and endothelial cells. These mesenchymal stromal cells are not only components of the parenchymal and vascular architecture, but also have a pivotal role in controlling TEC development, although their functions have been less extensively explored than TECs. Here, we review both the historical studies on and recent advances in our understanding of the contribution of such non-TEC stromal cells to thymic organogenesis and T cell development. In particular, we highlight the recently discovered functional effect of thymic fibroblasts on T cell repertoire selection.

Distribution of nerve fibers and nerve-immune cell association in mouse spleen revealed by immunofluorescent staining. Sci Rep 2020; 10:9850.

Abstract
The central nervous system regulates the immune system through the secretion of hormones from the pituitary gland and other endocrine organs, while the peripheral nervous system (PNS) communicates with the immune system through local nerve-immune cell interactions, including sympathetic/parasympathetic (efferent) and sensory (afferent) innervation to lymphoid tissue/organs. However, the precise mechanisms of this bi-directional crosstalk of the PNS and immune system remain mysterious. To study this kind of bi-directional crosstalk, we performed immunofluorescent staining of neurofilament and confocal microscopy to reveal the distribution of nerve fibers and nerve-immune cell associations inside mouse spleen. Our study demonstrates (i) extensive nerve fibers in all splenic compartments including the splenic nodules, periarteriolar lymphoid sheath, marginal zones, trabeculae, and red pulp; (ii) close associations of nerve fibers with blood vessels (including central arteries, marginal sinuses, penicillar arterioles, and splenic sinuses); (iii) close associations of nerve fibers with various subsets of dendritic cells, macrophages (Mac1+ and F4/80+), and lymphocytes (B cells, T helper cells, and cytotoxic T cells). Our data concerning the extensive splenic innervation and nerve-immune cell communication will enrich our knowledge of the mechanisms through which the PNS affects the cellular- and humoral-mediated immune responses in healthy and infectious/non-infectious states.

Abstract
Neural regulation of the function of the gastrointestinal tract (GIT) relies on a delicate balance of the two divisions of its nervous system, namely, the intrinsic and extrinsic divisions. The intrinsic innervation is provided by the enteric nervous system (ENS), whereas the extrinsic innervation includes sympathetic/parasympathetic nerve fibers and extrinsic sensory nerve fibers. In the present study, we used immunofluorescent staining of neurofilament-heavy (NF-H) to reveal the distribution of nerve fibers and their associations with immune cells inside mouse Peyer's patches (PP), an essential part of gut-associated lymphoid tissue (GALT). Our results demonstrate (1) the presence of an extensive meshwork of NF-H-immunoreactive presumptive nerve fibers in all PP compartments including the lymphoid nodules, interfollicular region, follicle-associated epithelium, and subepithelial dome; (2) close associations/contacts of nerve fibers with blood vessels including high endothelial venules, indicating neural control of blood flow and immune cell dynamics inside the PP; (3) close contacts between nerve fibers/endings and B/T cells and various subsets of dendritic cells ( e.g., B220⁻, B220⁺, CD4⁻, CD4⁺, CD8⁻, and CD8⁺). Our novel findings concerning PP innervation and nerve-immune-cell contacts in situ should facilitate our understanding of bi-directional communications between the PNS and GALT. Since the innervation of the gut, including PP, might be important in the pathogenesis and progression of some neurological, infectious, and autoimmune diseases, e.g., prion diseases and inflammatory bowel disease, better knowledge of PNS-immune system interactions in the GALT (including PP) should benefit the development of potential treatments for these diseases via neuroimmune manipulations.

The central nervous system impacts the immune system mainly by regulating the systemic concentration of humoral substances, whereas the peripheral nervous system (PNS) communicates with the immune system specifically according to local "hardwiring" of sympathetic/parasympathetic (efferent) and sensory (afferent) nerves to the primary and secondary lymphoid tissue/organs (e.g., thymus spleen and lymph nodes). In the present study, we use immunofluorescent staining of neurofilament-heavy to reveal the distribution of nerve fibers and the nerve-immune cell neighborhood inside the mouse thymus. Our results demonstrate (a) the presence of an extensive meshwork of nerve fibers in all thymic compartments, including the capsule, subcapsular region, cortex, cortico-medullary junction and medulla; (b) close associations of nerve fibers with blood vessels (including the postcapillary venules), indicating the neural control of blood circulation and immune cell dynamics inside the thymus; (c) the close proximity of nerve fibers to various subsets of thymocytes (e.g., CD4+, CD8+ and CD4+CD8+), dendritic cells (e.g., B220+, CD4+, CD8+ and F4/80+), macrophages (Mac1+ and F4/80+) and B cells. Our novel findings concerning thymic innervation and the nerve-immune cell neighborhood in situ should facilitate the understanding of bi-directional communications between the PNS and primary lymphoid organs. Since the innervation of lymphoid organs, including the thymus, may play essential roles in the pathogenesis and progression of some neuroimmune, infectious and autoimmune diseases, better knowledge of PNS-immune system crosstalk should benefit the development of potential therapies for these diseases.
