In immunoelectrophoretic analyses one common antigen was demonstrated in antigen preparations from herpes simplex virus types 1- and 2- (HSV-1 and HSV-2), bovine herpes mammillitis (BHM) virus-, and B virus-infected cells solubilized by Triton X-100. The antigen was also demonstrated in solubilized purified HSV-1 and BHM virus. The common antigen was identified as antigen 11 of HSV-1 or HSV-2. ...

The detection of an inherited X-linked serum system in man, disclosed by a heteroantisenim made specific by absorption, is described. These studies suggest that the antigen, demonstrated by the specific antiserum, resides in the alpha(2)-macroglobulin fraction of serum. The system has been named the Xm system, where X refers to the localization of the gene on the X chromosome, and the m indicat...

Two BALB radiation leukemias are strongly rejected by hybrids of BALB with certain other mouse strains, although BALB mice themselves exhibit no detectable resistance whatever. Hybrids immunized with progressively increased inocula are resistant to 200 x 10(6) or more leukemia cells; their serum is cytotoxic for the leukemia cells in vitro and protects BALB mice against challenge with these BAL...

In some mating combinations in rats, there is a maternal antibody response to the maternal antigenic components of the placenta without any previous immunization of the mother. The highest response occurs in the WF (u) female mated to the DA (a) male, and it is against a unique MHC-encoded class I antigen, the Pa antigen, and not against the major allele-specific transplantation antigen of the ...

Investigations into the possibility that X (an antigen consistently present in aspirated odontogenic keratocysts, but not in most fluids from other cyst types), represented a keratinocyte component failed to identify the antigen as a keratin, involucrin, or one of the blood group substances. Antigen X was detected in human mixed and parotid saliva and in colostrum, as well as in a commercially ...

The palmitoyl derivative of the linear polypeptide of poly-(L-Glu-L-Lys-L-Phe)n (GLphi) can be coupled to spleen cells directly. The intravenous administration of 2 X 10(5)--3 X 10(7) GLphi-coupled syngeneic spleen cells induces GL-phi-specific suppressor T cells in C57BL/6 nonresponder mice. The suppression is antigen specific and can be detected by the inhibition of the primary GLphi plaque-f...

The article is devoted to an ambiguous and problematic issue related Ukrainian- Basque linguistic ties. By lexical parallels (they can also be called conditional isoglosses) the author of this study means hypothetical borrowings-internationalisms (Europeanisms), presumably origin. Examples basquisms in Ukrainian language (багнет, більярд, анчоус, i.e. ʽbayonet, billiard, anchovy’) have been giv...

The present studies were carried out to characterize the cellular interactions involved in the activation and function of the antigen-specific and antigen-nonspecific T suppressor (Ts) cells that regulate the IgG responses of Lyb-5-B cells. The in vitro activation of both Lyt-1+2- antigen-nonspecific Ts cells and Lyt-1-2+ antigen-specific Ts cells was shown to require the interaction of accesso...
