Background: NK (natural killer) and NKT (natural killer T) cells, as components of innate immune system, play a crucial role in tumor progression and dissemination. Objective: To investigate the percentages of NK cells, NKT cells, iNKT (invariant natural killer T) cells, total T lymphocytes as well as activated T lymphocytes, in tumor draining lymph nodes (TDLN...

Background: Systemic Lupus Eyrythematosus (SLE) is an autoimmune disease charac-terized by antibodies to nuclear antigens, particularly anti-dsDNA. Imbalance between production and destruction of immune cells causes cytopenia. Sex hormones have im-munomodulatory effects; estrogen increases the production of autoantibodies in SLE prone NZB/NZW mice. Objective: To investigate the relationship bet...

background: lymphocyte subsets enumeration is considered prominent in the management of primary and acquired immunodeficiency disorders. because of local variations due to race, age, gender, and environmental conditions on lymphocyte subsets, and to improve the accuracy of interpretation of laboratory findings, reference intervals must be determined in every population. objective: to establish ...

To evaluate the associations among immune cells (T-cells, B-cells, Macrophages and NK cells) in human endometrium during mid-luteal phase of menstrual cycle. Endometrial biopsies were obtained from 116 women (7 days after LH surge) natural cycles. The presence CD3-positive (T-cells), CD4-positive (T-helpers), CD8-positive (T-killers), CD14-positive (Macrophages), CD68-positive CD56-positive (NK...

Abstract Background Patients suffering from IBD frequently suffer chronic visceral pain, severely affecting quality of life. To better understand factors impacting pain signaling by enteric nervous system (ENS) neuronal cells, we analyzed the infiltration myenteric plexus (MP) ENS inflammatory cell populations. In detail, characterized (i) immune populations infiltrating MP, (ii) neurotransmitt...

the number and function of human natural killer (nk) cells are generally assessed to monitor the baseline of immune function, the effect of treatment, the progress of malignancy or metastases and diseases. nk cells recognise and kill target cells in the absence of prior sensitisation and are able to defend the host from infection or prevent the progression of a disease. human nk cells express c...

Abstract A cognate antigen engagement of TCR induces a conformation change in the CD3 complex (CD3Δc) that is required for productive T cell activation. CD3Δc fails when TCRs interact with poorly immunogenic antigens, like many tumor-associated-antigens (TAAs), which do not active cells. Anti-CD3 monovalent Fab fragments (Mono-Fabs) bound to mimic CD3Δc, producing “co-potentiation” associated w...
