The permanent activation of the transcription factor nuclear factor-nB (NF-nB) in pancreatic cancer cells is associated with a profound resistance towards chemotherapy. In the present study, we show that chemoresistant pancreatic cancer cell lines exhibiting constitutive NF-nB activity (i.e., PancTu-1, BxPc3, and Capan-1) express significantly elevated levels of the E3-ubiquitin ligase receptor...

objective: th17 cells are known to be involved in some types of inflammations and autoimmune disorders. rorc2 is the key transcription factor coordinating th17 cell differentiation. thus, blocking rorc2 may be useful in suppressing th17-dependent inflammatory processes. the aim was to silence rorc2 by specific sirnas in naïve t cells differentiating to th17. time-dependent expression of rorc2 a...

objective(s): systemic lupus erythematosus (sle) is a multi-factorial autoimmune disease which may be characterized by t lymphocytes dysfunctions. th17 cells have been identified as new effector cells, which play an important role in the pathogenesis. in recent years, immunomodulatory effect of vitamin d3 has been noticed. in the present experiment, the effect of vitamin d3 on the expression of...

B-1 lymphocytes are the predominant cells in mouse peritoneal cavity. They express macrophage and lymphocyte markers and are divided into B-1a, B-1b and B-1c subtypes. The role of B-1 cells is not completely clear, but they are responsible for natural IgM production and seem to play a regulatory role. An enriched B-1b cell population can be obtained from non-adherent peritoneal cell cultures, a...

BACKGROUND Hyporesponse to erythropoietin is a common problem seen in around 5-10% of patients. Recently the focus from these remediable factors has been shifted to the non-modifiable innate factors i.e polymorphism of ACE and IL-1B gene and studies have shown that DD genotype and IL-1B CC genotype have lower erythropoietin requirement. The aim of our study was to evaluate the role of ACE and I...

objective: common variable immunodeficiency (cvid) is one of the most frequent cases of primary immunodeficiency. it is likely that this heterogeneous disease is caused by several distinct genetic disorders. the activation-induced cytidine deaminase (aid) enzyme is involved in class switching, somatic hypermutation (shm) and processes associated with gene conversion in the germinal center. in o...

there are confirmed beneficiary effects of exercise on atherosclerotic inflammation of ischemia-associated heart diseases. the purpose of this study was to evaluate the effect of aerobic exercise on t-regulatory cell markers of il-35 as well as foxp3 and t-helper2 marker of il-33 in patients with ischemic heart disease (ihd). this research was performed on 44 asymptomatic male patients with isc...

CCAAT/enhancer binding protein c (C/EBPc) is a member of the C/EBP family of transcription factors, which lacks known activation domains. C/EBPc was originally described as an inhibitor of C/EBP transactivation potential. However, previous study demonstrates that C/EBPc augments the C/EBPb stimulatory activity in lipopolysaccharide induction of IL-6 promoter in a B lymphoblast cell line. These ...

Th17 cells have been identified as new effector cells, which play an important role in the pathogenesis. In recent years, immunomodulatory effect of vitamin D3 has been noticed.

We show, in a series of established experimental breast adenocarcinomas and fibrosarcomas induced by carcinogen de novo in mice, that the therapeutic efficacy of doxorubicin treatment is dependent on CD8 T cells and IFN-g production. Doxorubicin treatment enhances tumor antigen–specific proliferation of CD8 T cells in tumor-draining lymph nodes and promotes tumor infiltration of activated, IFN-...
