Methods Our group formed a multidisciplinary group to study the immunobiology of HNSCC and to develop strategies to effectively treat this disease. Over the past 3 years we have collected and processed more than 192 HNSCC specimens. Starting in June of 2013 we began to set up cultures of tumor-infiltrating lymphocytes (TIL) from specimens with sufficient numbers of cells isolated by triple enzy...
In the paper we describe the method of encoding communication of agents in a multi-agent system (MAS). The autonomous agents communicate with each other by exchanging messages formulated in a near-to-natural language. Transparent Intensional Logic (TIL) is an expressive system primarily designed for the logical analysis of natural language; thus we make use of TIL as a tool for encoding the sem...
Addition of IL-4 (1,000 U/ml) to either high or low concentrations of IL-2 augmented tumor-infiltrating lymphocytes (TIL) growth from human melanoma. Weekly restimulation with irradiated tumor cells in conjunction with IL-4 allowed enhanced growth of TIL. With low-dose IL-2 (10 U/ml) and IL-4, expanded TIL had little cytolytic activity against Daudi or allogeneic tumors. Further, IL-4 augmented...
Programmed Death 1 (PD-1) and T cell Ig and mucin domain-3 protein (Tim-3) are two immune checkpoint receptors (ICR) highly co-expressed on tumor infiltrating T lymphocytes (TIL). PD-1 has been shown to inhibit T cell activation and type 1 T cell responses, while Tim-3 has been proposed as a further marker of exhaustion on TIL [1,2], leading us to investigate the phenotypic and functional chara...
Manipulation of T-cell co-inhibitory molecules, such as CTLA-4, PD-1, and BTLA has recently moved to the forefront of cancer immunotherapy. Although these molecules serve as inhibitors of T-cell activation, they are also biomarkers for activated T cells and may in fact have positive immune regulatory functions under certain circumstances. Recently, we demonstrated an unexpected positive associa...
Tumor immunologic microenvironment is strongly involved in tumor progression and the presence of tumor infiltrating lymphocytes (TIL) with different phenotypes has been demonstrated to be of prognostic relevance in different malignancies. We investigated whether TIL infiltration of tumor tissues could also predict the outcome of prostate cancer patients. To this end, we carried out a retrospect...
Adoptive T-cell therapies for cancer can induce tumor responses in patients with metastatic melanoma, synovial sarcoma, and B-cell malignancies. However, no cellular therapy has demonstrated activity in a common epithelial tumor. Adoptive transfer of tumor infiltrating lymphocytes (TIL) has high response rates and can induce complete and durable tumor regression in metastatic melanoma. We sough...
چکیده زمینه و هدف: مطالعات انجام شده نشان می دهد که تابش یک یا دو بسامد به صورت پیوسته و یا متناوب در شدت پایین در درمان سرطان در مدل حیوانی کارآمد است. اثر هم افزایی امواج فراصوت 150 کیلوهرتز با شدت کم، در ترکیب با داروی ضد سرطان دوکسوروبیسین ( DOX ) بر روی رشد تومور آدنوکارسینومای پستان در شرایط درون تنی در مدل حیوانی موش ماده ی نژاد Balb/C بررسی گردید. روش تحقیق: در این مطالعه ی تجربی ...
To characterize the origin of living polymerization with nonmetallocene titanium-based catalysts containing o-fluoroaryl substituents, ethene polymerization by an o-fluorinated bis(enolatoimine) titanium catalyst and its nonfluorinated counterpart has been studied by multinuclear NMR spectroscopy by using methylaluminoxane (MAO) or AlMe(3)/CPh(3)B(C(6)F(5))(4) as activators. Formation of ion pa...
The detection and characterization of antigens expressed during the progression of carcinogenesis is still a major goal for tumour immunology. We describe a possible new way for defining human tumour specific antigens with the use of scFv phage display technology [1]. An attractive hypothesis is that tumour infiltrating lymphocytes (TIL) are accumulated in the tumour tissue because of their uni...
