[The histopathological features of the severe intoxication with amatoxin (toxin contained in Amanita phalloides mushrooms)].

Eating mushrooms known to contain amatoxin is fraught with serious complications. The analysis of the relevant literature publications revealed no article with the description of the histological picture of the internal organs in the subjects intoxicated with amatoxin. It is known, however, that such poisoning is associated with the severe irreversible injuries to all intracellular protein structures the character of which depends on time.

[Effect of nucleocapsid on multimerization of gypsy structural protein Gag].

The structural protein (Gag) of the gypsy Drosophila retrovirus lacks matrix, but contains capsid and nucleocapsid domains. The Gag forms virus-like particles in a bacterial cell; besides, its capsid alone is able to form aggregates. However, aggregates assembled from the capsid were variable in size and displayed much less organization than particles formed by the whole Gag.

[The structural protein Gag of the gypsy retrovirus forms virus-like particles in the bacterial cell].

The amino acid sequence of the drosophila retrovirus MDG4 (gypsy) structural protein Gag does not contain a canonical motif known for the majority of vertebrate retroviruses. Moreover, the protein translation can theoretically begin with two separated initiation codons located within its unique open reading frame. We designed constructs for expression of two theoretically possible variants of Gag polypeptide and investigated an ability of the each product to form virus-like particles in the bacterial cell, i.
