Experiment K-6-23. Effect of spaceflight on levels and function of immune cells
Author(s): Mandel, A. D.; Sonnenfeld, G.; Berry, W.; Taylor, G.; Wellhausen, S. R.; Konstantinova, I.; Lesnyak, A.; Fuchs, B.
Abstract: Two different immunology experiments were performed on samples received from rats flown on Cosmos 1887. In the first experiment, rat bone marrow cells were examined in Moscow for their response to colony stimulating ...

Effects of isolation on interferon production and hematological and immunological parameters
Author(s): Sonnenfeld, G.; Measel, J.; Loken, M. R.; Degioanni, J.; Follini, S.; Galvagno, A.; Montalbini, M.
Abstract: A 27-year-old woman was maintained in an isolated state for 131 days in Carlsbad Caverns, New Mexico. Her diet was vitamin D-depleted. Determinations on the effects of such isolation on levels and activities of peripheral ...

Antiorthostatic suspension stimulates profiles of macrophage activation in mice
Author(s): Miller, E. S.; Bates, R. A.; Koebel, D. A.; Sonnenfeld, G.
Abstract: The antiorthostatic suspension model simulates certain physiological effects of spaceflight. We have previously reported BDF1 mice suspended by the tail in the antiorthostatic orientation for 4 days express high levels of ...

Antiorthostatic suspension as a model for the effects of spaceflight on the immune system
Author(s): Chapes, S. K.; Mastro, A. M.; Sonnenfeld, G.; Berry, W. D.
Abstract: We describe the use and appropriateness of antiorthostatic suspension in immunological investigations. This manuscript describes the model and discusses how well data obtained by using the model correlate with spaceflight ...

2-deoxy-D-glucose-induced metabolic stress enhances resistance to Listeria monocytogenes infection in mice
Author(s): Miller, E. S.; Bates, R. A.; Koebel, D. A.; Fuchs, B. B.; Sonnenfeld, G.
Abstract: Exposure to different forms of psychological and physiological stress can elicit a host stress response, which alters normal parameters of neuroendocrine homeostasis. The present study evaluated the influence of the ...

Immune changes in test animals during spaceflight
Author(s): Lesnyak, A. T.; Sonnenfeld, G.; Rykova, M. P.; Meshkov, D. O.; Mastro, A.; Konstantinova, I.
Abstract: Over the past two decades, it has become apparent that changes in immune parameters occur in cosmonauts and astronauts after spaceflight. Therefore, interest has been generated in the use of animal surrogates to better ...

Stress-induced alterations in interferon production and class II histocompatibility antigen expression
Author(s): Sonnenfeld, G.; Cunnick, J. E.; Armfield, A. V.; Wood, P. G.; Rabin, B. S.
Abstract: Mild electric foot-shock has been shown to be a stressor that can alter immune responses. Male Lewis rats were exposed to one session of 16 5.0-s 1.6-mA foot-shocks. Production of interferon-gamma by splenocytes in response ...

Immune responses in space flight
Author(s): Sonnenfeld, G.
Abstract: Space flight has been shown to have profound effects on immunological parameters of humans, monkeys and rodents. These studies have been carried out by a number of different laboratories. Among the parameters affected are ...
