Abstract
BACKGROUND Increased epithelial permeability has been reported in allergic rhinitis, with histamine and type-2 inflammation being responsible for tight junction dysfunction. The impact of an epithelial barrier defect on allergic sensitization and mast cell (MC) degranulation remains speculative. METHODS Transepithelial passage of allergens was evaluated on primary human nasal epithelial cell cultures. Active sensitization was attempted by repeated intranasal ovalbumin (OVA) applications in Naïve mice. In a passive sensitization model, mice were injected with IgE to Dermatophagoides pteronyssinus (rDer p)2 and then exposed intranasally to the allergen. Chitosan was used to disrupt nasal epithelial integrity in vitro and in vivo. RESULTS Chitosan strongly reduced transepithelial electrical resistance and facilitated transepithelial allergen passage in cultured primary nasal epithelial cells. In vivo, intranasal chitosan affected occludin expression and facilitated allergen passage. After epithelial barrier disruption, intranasal OVA application induced higher OVA-specific IgG1 and total IgE in serum, and increased eosinophilia and interleukin-5 in bronchoalveolar lavage (BAL) compared to sham-OVA mice. Chitosan exposure, prior to rDer p2 allergen challenge in passively sensitized mice, resulted in increased β-hexosaminidase levels in serum and BAL compared to sham-rDer p2 mice. Intranasal treatment with the synthetic glucocorticoid fluticasone propionate prevented chitosan-induced barrier dysfunction, allergic sensitization, and MC degranulation. CONCLUSION Epithelial barrier dysfunction facilitates transepithelial allergen passage, allergic sensitization, and allergen-induced MC degranulation even in the absence of inflammatory environment. These results emphasize the crucial role of an intact epithelial barrier in prevention of allergy.

Abstract
Allogeneic hematopoietic stem cell transplantation (alloHSCT) produces -similar to the long-established graft-versus-leukemia effect- graft-versus-solid-tumor effects. Clinical trials reported response rates of up to 53%, occurring mostly but not invariably in association with full donor chimerism and/or graft-versus-host disease. Although donor-derived T cells are considered the principal effectors of anti-tumor immunity after alloHSCT or donor leukocyte infusion (DLI), growing evidence indicate that recipient-derived immune cells may also contribute. Whereas the role of recipient-derived antigen-presenting cells in eliciting graft-versus-host reactions and priming donor T cells following DLI is well known, resulting inflammatory responses may also break tolerance of recipient effector cells towards the tumor. Additionally, mouse studies indicated that post-transplant recipient leukocyte infusion produces anti-leukemia and anti-solid-tumor effects that were exclusively mediated by recipient-type effector cells, without graft-versus-host disease. Here, we review current preclinical and clinical evidence on graft-versus-solid-tumor effects and growing evidence on the effector role of recipient-derived immune cells in the anti-tumor effect of alloHSCT.

Abstract
Allogeneic hematopoietic stem cell transplantation is an emerging treatment option for solid tumors because of its capacity to elicit immune graft-versus-tumor effects. However, these are often limited and associated with GvHD. Adoptive recipient leukocyte infusion (RLI) was shown to enhance anti-tumor responses of allogeneic bone marrow transplantation in murine neuroblastoma (Neuro2A)-bearing chimeras. In contrast to the clinically used donor leukocyte infusion, the RLI anti-tumor effect-elicited by host-versus-graft lymphohematopoietic reactivity-does not cause GvHD; however, the tumor growth-inhibitory effect is incomplete, because overall survival is not prolonged. Here, we studied the anti-solid tumor mechanisms of RLI with the objective to improve its efficacy. Host-versus-graft reactivity following RLI was associated with a systemic cytokine storm, lymph node DC activation, and systemic expansion of host-derived IFN-γ-expressing CD4+ T cells and IFN-γ-and granzyme B-expressing CD8+ T cells, which acquired killing activity against Neuro2A and third-party tumor cells. The tumor showed up-regulation of MHC class I and a transient accumulation of IFN-γ-and granzyme B-expressing CD8+ T cells: the intra-tumor decline in cytotoxic CD8+ T cells coincided with a systemic-and to a lesser extent intra-tumoral-expansion of MDSC. In vivo MDSC depletion with 5-FU significantly improved the local tumor growth-inhibitory effect of RLI as well as overall survival. In conclusion, the RLI-induced alloreactivity gives rise to a host-derived cytotoxic T-cell anti-neuroblastoma response, but also drives an expansion of host-type MDSC that counteracts the anti-tumor effect. This finding identifies MDSC as a novel target to increase the effectiveness of RLI, and possibly other cancer immunotherapies.
