Article
Full-text available
T cell immunity is crucial for the control of SARS-CoV-2 infections and has been widely studied on a quantitative level. However, quality of responses, in particular of CD8⁺ T cells, has only been marginally investigated so far. Here, we isolate T cell receptor (TCR) repertoires specific for immunodominant SARS-CoV-2 epitopes restricted to common H...
Preprint
T cell immunity is crucial for the control of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections and has been widely characterized on a quantitative level. In contrast, the quality of such T cell responses has been poorly investigated, in particular in the case of CD8+ T cells. Here, we explored the quality of SARS-CoV-2-specif...
Article
Background: Fingolimod (FTY) applied as treatment regimen of relapsing-remitting multiple sclerosis (RRMS) induces downregulation of sphingosine-1-phosphate receptors on the lymphocytes. As a result CC chemokine receptor type 7 (CCR7) expressing lymphocytes are retained within the peripheral lymph nodes thus suppressing their accumulation into the...
Article
Antigen‐specific T cells isolated from healthy individuals (HIs) have shown great therapeutic potential upon adoptive transfer for the treatment of viremia in immunosuppressed patients. The lack of comprehensive data on the prevalence and characteristics of leukemia associated antigen (LAA)‐specific T cells in HIs still limits such an approach for...
Article
Full-text available
Background: The NK-92/5.28.z cell line (also referred to as HER2.taNK) represents a stable, lentiviral-transduced clone of ErbB2 (HER2)-specific, second-generation CAR-expressing derivative of clinically applicable NK-92 cells. This study addresses manufacturing-related issues and aimed to develop a GMP-compliant protocol for the generation of NK-...
Article
The advent of novel strategies to generate leukemia-associated-antigen (LAA)-specific T cells for adoptive immunotherapies creates a demand for standardized good laboratory practice (GLP)-compliant enumeration assays to provide a secure clinical environment-whether it is to identify potential donors, define therapeutic doses for transplantation, or...
Article
Cytomegalovirus (CMV) infection is a common, potentially life-threatening complication following allogeneic hematopoietic stem cell transplantation (allo-HSCT). We assessed prospectively safety and efficacy of stem cell-donor- or third-party-donor-derived CMV-specific T cells for the treatment of persistent CMV infections after allo-HSCT in a phase...
Article
Full-text available
Natural killer (NK) cells are increasingly considered as immunotherapeutic agents in particular in the fight against cancers. NK cell therapies are potentially broadly applicable and, different from their T cell counterparts, do not cause graft-versus-host disease. Efficacy and clinical in vitro or in vivo expansion of primary NK cells will however...
Article
While adoptive transfer of virus antigen specific T cells has shown to be effective in therapy of resistant recurrent viremia which is frequently associated with the lack of protective immunity following hematopoietic stem cell transplantation, the transfer of leukemia associated antigen specific (LAA) T cells is less implemented and appears to dep...
Article
Full-text available
Recently, mesenchymal stromal cell-derived extracellular vesicles (MSC-EVs) have been suggested as an alternative to MSCs for the treatment of various inflammatory disorders. However, while a first case report observed beneficial therapeutic effects of repeated MSC EV infusions in a patient with therapy refractory graft versus host disease (GvHD),...
Article
Full-text available
Natural killer (NK) cells are an important effector cell type for adoptive cancer immunotherapy. Similar to T cells, NK cells can be modified to express chimeric antigen receptors (CARs) to enhance antitumor activity, but experience with CAR-engineered NK cells and their clinical development is still limited. Here, we redirected continuously expand...
Article
Full-text available
Background aims Reactivation of cytomegalovirus (CMV) after hematopoietic stem cell transplantation remains a major cause of morbidity despite improved antiviral drug therapies. Selective restoration of CMV immunity by adoptive transfer of CMV-specific T cells is the only alternative approach that has been shown to be effective and non-toxic. We de...
Article
While EGFRvIII appears a logical target for immunotherapy, only a subpopulation of tumor cells express EGFRvIII and immune escape has been demonstrated. ErbB2 is overexpressed in a substantial proportion of glioblastomas and has been successfully utilized in immunotherapies. Natural killer (NK) cells are the first line of defense against viral infe...
Article
Full-text available
Patients undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT) are threatened by potentially lethal viral manifestations like cytomegalovirus (CMV) reactivation. Because the success of today's virostatic treatment is limited by side effects and resistance development, adoptive transfer of virus-specific memory T cells derived fr...
Conference Paper
Introduction: Recently, several groups have reported the secretion of membrane vesicles (MVs) from various cell types, including mesenchymal stromal cells (MSCs). Interest in MVs has intensified due to the rec- ognition of their role as an important component of the intracellular microenvironment. Therefore, our work aimed to characterize MSC-deriv...

Article
Full-text available
Recent results on the biology of plasma cells have shown that these cells can survive as long as memory B cells. Possibly, such long-lived plasma cells are also involved in the production of autoantibodies. Here, we discuss the potential involvement of long-lived plasma cells in the pathogenesis of autoimmune disease and the consequences it has for...
Article
Full-text available
Autoimmune phenomena may precede or accompany lymphoid malignancies, especially B-chronic lymphocytic leukemia (B-CLL). We report a patient with a 7-year history of primary (idiopathic) cold agglutinin (CA) disease in whom B-CLL subsequently developed. Immunophenotyping and single-cell reverse transcription-polymerase chain reaction (RT-PCR) were a...
Article
A number of autoantibodies play a significant role in collagen vascular diseases and represent diagnostic markers of some of these entities. Despite increasing knowledge of these serological findings, data are limited about potential disturbances of precursor cells that finally lead to the autoantibody producing plasma cells. Recent evidence of dis...

In patients with active systemic lupus erythematosus (SLE), a marked B lymphocytopenia was identified that affected CD19(+)/CD27(-) naive B cells more than CD19(+)/CD27(+) memory B cells, leading to a relative predominance of CD27-expressing peripheral B cells. CD27(high)/CD38(+)/CD19(dim)/surface Ig(low)/CD20(-)/CD138(+) plasma cells were found at...
Article
Recent studies in mice have indicated that the long-lasting specific antibody responses seen after vaccination are probably due to the existence of long-lived plasma cells. Therefore, because the maintenance of humoral immunity does not necessarily reflect continuous restimulation of long-lived memory B cells, the question arises as to what degree...
