چکیده

Background The expression of catalytic phosphoinositol-3-kinase isoform δ (PI3Kδ) is restricted to the haematopoetic compartment. Accordingly, PI3Kδ serves as a drug target to eliminate leukaemic cells. However, we previously showed that PI3Kδ is indispensable for the function of natural killer (NK)-cells [1]. Thus, the therapeutic success of PI3Kδ inhibitors is likely to be compromised by unintended side effects on the immune system. Besides NK-cells, CD8 cytotoxic T-cells (CTLs) are well-known key players in natural host response against developing tumours and viral infections. In this study, we examine the role of PI3Kδ for CTL function and CTL-mediated tumour surveillance.

PI3Kδ Is Essential for Tumor Clearance Mediated by Cytotoxic T Lymphocytes

BACKGROUND PI3Kδ is a lipid kinase of the phosphoinositide 3-kinase class 1A family and involved in early signaling events of leukocytes regulating proliferation, differentiation and survival. Currently, several inhibitors of PI3Kδ are under investigation for the treatment of hematopoietic malignancies. In contrast to the beneficial effect of inhibiting PI3Kδ in tumor cells, several studies rep...

The PI3Kδ-Selective Inhibitor Idelalisib Minimally Interferes with Immune Effector Function Mediated by Rituximab or Obinutuzumab and Significantly Augments B Cell Depletion In Vivo

Idelalisib is a highly selective oral inhibitor of PI3Kδ indicated for the treatment of patients with relapsed chronic lymphocytic leukemia in combination with rituximab. Despite additive clinical effects, previous studies have paradoxically demonstrated that targeted therapies potentially negatively affect anti-CD20 mAb effector mechanisms. To address these potential effects, we investigated t...

Granzyme C supports efficient CTL-mediated killing late in primary alloimmune responses.

It is well established that granzymes A and B play a role in CTL killing of target cells by the perforin-dependent granule exocytosis pathway. The functions of multiple additional granzymes expressed in CTL are less well defined. In the present studies, CTL generated from mice deficient in dipeptidyl peptidase 1 (DPP1) were used to investigate the contribution of granzyme C to CTL killing of al...

CTL Responses to DCs Stimulated with Leishmania Antigens Detected by DCs Expressing Leishmania gp63

Background: Leishmania is a pathogenic parasite which infects mononuclear cells in vertebrate hosts. Different strategies have been taken to develop immunity against Leishmania . DCs loaded with immunogenic antigen have resulted in different levels of Th1-type immune response and cytotoxic T lymphocytes (CTL) activity. Objective: To evaluate the potency of DCs primed with soluble Leishmania mex...

Kinetics of Primary and Memory Cytotoxic T Lymphocyte Responses to Herpes Simplex Virus 1 Infection: Granzyme B Mediated CTL Activity

Background: Herpes simplex virus type 1 is one of the most common viruses among human population. Studies demonstrate the essential role of cell mediated immunity, especially CD8+ T cells, in prevention and clearance of HSV1. Objective: It is of great importance to improve our knowledge about the kinetics of CTL responses to primary and secondary HSV-1 infection. Methods: Using a sensitive tech...
