Immune human lymphocytes produce an acid-labile α-interferon
We have described in this paper a novel human interferon (IFN) with antigenic and cross-species reactivity of alpha-IFN and physicochemical properties of gamma-IFN. This IFN is produced by normal peripheral blood mononuclear cells during an immune response but has also been associated with autoimmune disease (10). The system described here will be useful in elucidating the biological significan...
متن کاملHuman monocytes can produce tissue-type plasminogen activator
Evidence has previously been presented that monocytes and macrophages produce urokinase-type plasminogen activator. We have shown for the first time that human monocytes, when stimulated appropriately in vitro, can produce tissue type-plasminogen activator (t-PA) of 70 kD. Detection of t-PA mRNA was consistent with the biochemical and immunological characterization of t-PA produced by human mon...
متن کاملStructural Plasticity Can Produce Metaplasticity
BACKGROUND Synaptic plasticity underlies many aspect of learning memory and development. The properties of synaptic plasticity can change as a function of previous plasticity and previous activation of synapses, a phenomenon called metaplasticity. Synaptic plasticity not only changes the functional connectivity between neurons but in some cases produces a structural change in synaptic spines; a...
متن کاملCan cirrus clouds produce glories?
A vague glory display was photographed over central Utah from an airplane beginning its descent through a cirrus cloud layer with an estimated cloud top temperature of -45 and -55 degrees C. Photographic analysis reveals a single reddish-brown ring of 2.5-3.0 degrees radius around the antisolar point, although a second ring appeared visually to have been present over the brief observation perio...
متن کاملInducible Expression of Human Gamma Interferon
Background:The premature termination of high producer clones, which will be killed due to cell proliferation and proteins production antagonism, is one of the basic drawback in recombinant proteins technology. Furtheremore, it is supposed some toxic proteins like interferon which we intended to clone and express, inhibit host cells’ proliferation. So, it is necessary to tightly control IFN-γ pr...
