Shedding of ICAM-1 from human melanoma cell lines induced by IFN-gamma and tumor necrosis factor-alpha. Functional consequences on cell-mediated cytotoxicity.

Journal of Immunology, 1991
ICAM-1-mediated cell-cell adhesion is essential for various immunologic functions, including non-MHC-restricted cytotoxicity. The present study was designed to establish whether shedding of ICAM-1 from melanoma cells occurred and to characterize the ...

Ultra‐Effective Light‐Activated Antibacterial Activity via Carboxyl Functionalized Graphene Quantum Dots and Films

Advanced Functional Materials, EarlyView.
Carboxyl‐functionalized graphene quantum dots (cGQDs) exhibit high singlet oxygen quantum yield due to strong spin–orbit coupling. cGQDs achieve minimum bactericidal concentration of only 0.4 µg mL−1 against S. aureus under low‐intensity illumination.

Strange Attractor in Immunology of Tumor Growth [PDF]

arXiv, 1997
The time delayed cytotoxic T-lymphocyte response on the tumor growth has been developed on the basis of discrete approximation (2-dimensional map). The growth kinetic has been described by logistic law with growth rate being the bifurcation parameter.

Cancer: The Great Challenge for Immunology [PDF]

, 1977
The existence of immunity to cancer was postulated by the eminent scientists who helped to establish the discipline of immunology. In 1907 Clowes suggested that human resistance to cancer resulted from what we today call “immune surveillance.” During the

Engineered Peptides‐Based Hybrid‐Nested Microneedle Effectively Treat Biofilm‐Infected Diabetic Wounds

Advanced Functional Materials, EarlyView.
A hybrid‐nested microneedle/cryogel scaffold (MQW‐CMg‐MOF) is designed for efficient biofilm removal and accelerated healing of diabetic wounds. The scaffold shows substantial biofilm removal in vitro and in a preclinical diabetic swine biofilm‐infected wound model compared to the control.

Role of alloantigens in natural killing. Allogeneic but not autologous tumor biopsy cells are sensitive for interferon-induced cytotoxicity of human blood lymphcoytes

Journal of Experimental Medicine, 1980
Blood lymphocytes of patients with solid tumors were assayed for cytotoxicity against autologous and allogeneic primary tumor cells. The lymphocytes killed autologous tumor cells in 7 of 25 cases (28%) and allogeneic tumor cells in 2 of 37 tests (5 ...

Biocompatibility of Water‐Dispersible Pristine Graphene and Graphene Oxide Using a Close‐to‐Human Animal Model: A Pilot Study on Swine

Advanced Healthcare Materials, EarlyView.
Graphene‐based materials are attracting considerable interest for biomedical applications. Analysis of their biocompatibility is required before their clinical translation, and swine represents an excellent close‐to‐human model. This study evaluates the toxicological and immunological impact of pristine graphene and graphene oxide through a compendium ...

Dissociation of Its Opposing Immunologic Effects Is Critical for the Optimization of Antitumor CD8+ T-Cell Responses Induced by Interleukin 21

Clinical Cancer Research, 2008
Purpose: Interleukin 21 (IL-21) is a promising new cytokine, which is undergoing clinical testing as an anticancer agent. Although IL-21 provides potent stimulation of CD8+ T cells, it has also been suggested that IL-21 is immunosuppressive by ...

Enhanced Bioprinting of 3D Corneal Stroma Patches with Reliability, Assessing Product Consistency and Quality through Optimized Electron Beam Sterilization

Advanced Healthcare Materials, EarlyView.
This study optimizes sterilization methods for bioprinted 3D corneal stroma patches made from cornea‐derived decellularized extracellular matrix (Co‐dECM) hydrogels and human keratocytes. It demonstrates the superiority of electron beam sterilization in preserving the mechanical, biochemical, and immunomodulatory properties of hydrogels, ensuring ...
