Cytotoxicity and Immunological Response of Gold and Silver Nanoparticles of Different Sizes
Small, 2009AbstractThe immunological response of macrophages to physically produced pure Au and Ag nanoparticles (NPs) (in three different sizes) is investigated in vitro. The treatment of either type of NP at ≥10 ppm dramatically decreases the population and increases the size of the macrophages.

SUMMARY Macrophages which are cytotoxic in vitro to tumour cells in an immunologically specific manner can be classified into (1) radiosensitive, cytotoxicity totally abolished by 500 R of X-rays; and (2) radioresistant, cytotoxicity unaffected by 500 R but partially ablated by 1,000 R.

The Journal of Immunology, 1990
Abstract Minor H incompatible P815 tumor cells inoculated into the anterior chamber (AC) of the eyes of BALB/c mice grow progressively, revealing this to be an immunologically privileged site. By contrast, a similar inoculation of tumor cells is rapidly rejected from nonprivileged ocular sites (subconjunctiva).

Viral-bacterial pneumonia in calves: effect of bovine herpesvirus-1 on immunologic functions.
Journal of Infectious Diseases, 1985The temporal relation between a lung infection with bovine herpesvirus-1, suppression of some immune functions, and susceptibility to secondary bacterial infection resulting in fibrinous pneumonia prompted a study to determine the mechanism(s) involved ...

Expert Opinion on Therapeutic Patents, 1994
At present it seems that the vast majority if not all HIV infections eventually progress to ADS, with inevitable mortality from characteristic infections, neoplasia or more direct central nervous system effects of the virus. This apparently new virus has been strikingly successful in evolutionary terms because of clinical latency and effective ...

Studies on the mechanism of antibody-dependent polymorphonuclear leukocyte-mediated cytotoxicity.
Journal of Immunology, 1977Human polymorphonuclear leukocytes (PMN) were cytotoxic to mammalian tumor cells (LSTRA) in the presence of anti-LSTRA serum as determined by a 51Cr release assay.

A longitudinal study of immunological parameters in multiple sclerosis
Journal of the Neurological Sciences, 1979Complement-dependent gliotoxic antibody activity was determined in 22 patients with multiple sclerosis (MS) and 19 normal control persons. Peripheral blood serum was collected from MS patients at about 4-week intervals for one year, and the results of cytotoxicity tests correlated with the course of disease.

An immunological suppressor cell inactivating cytotoxic T-lymphocyte precursor cells recognizing it
Nature, 1980The immune system does not normally react against self components. Originally, it was postulated that self-reactive cells were somehow deleted or blocked. More recent thinking is that such cells are suppressed by regulatory networks similar to those limiting the immune response against non-self determinants. Both mechanisms may exist. I describe here a

Immunologically Mediated Cytotoxicity against Human Eye Muscle Cells in Graves’ Ophthalmopathy*
The Journal of Clinical Endocrinology & Metabolism, 1986The possible roles of antibody-mediated complement-dependent cytotoxicity (AMC), antibody-dependent killer (K) cell-mediated cytotoxicity (ADCC), and spontaneous, natural killer (NK) cell-mediated cytotoxicity (NKC) against human eye muscle cells in the pathogenesis of Graves' ophthalmopathy were investigated, using as targets human eye muscle cells ...
