Seven spontaneous BALB/cfC3H mouse mammary tumors were heterogeneous in expression of murine mammary tumor virus-associated cell surface antigens. To determine the basis of this heterogeneity, cells from spontaneous tumors and from five subpopulations isolated from a single spontaneous tumor were examined for expression of viral antigens under both conventional conditions and conditions known t...

A study has been made of the immunospecific, apple-green staining patterns imparted by fluorescent antibody to Rous virus in frozen sections of wing tumors produced in young chickens by various initiating doses of virus. Variations in the cellular site (cytoplasm, cell membrane, and nucleus), the distribution (particulate or homogeneous), and the quantity (little or much) of Rous viral antigens...

in this study one lymph node from cow with viral lymphosarcoma and one lymph node from healthy cow were analyzed by three different methods for protein extraction, include simple homogenizing in pbs, sonication and phenol extraction. tumor antigen detection relies on immunoprecipitation followed by sds-page. in this experiment streptococcus pyogenes was used for purification of immune complexes...

As the COVID-19 epidemic is still ongoing, a more rapid detection of SARS-CoV-2 infection such as viral antigen-detection needs to be evaluated for early diagnosis disease. Here, we report dynamic changes antigens in nasopharyngeal swabs patients and its association with nucleic acid clearance clinical outcomes. Eighty-five were enrolled antigens, including 57 anti-SARS-CoV-2 antibody negative ...

Central European tick-borne encephalitis (TBE) is caused by a flavivirus vectored by the Ixodes ricinus tick. In severe infections, TBE presents as (myelo)meningoencephalitis with considerable mortality. Characteristic neuropathologic changes feature a multinodular to patchy polioencephalomyelitis accentuated in spinal cord, brainstem, and cerebellum. Visualization of viral infection by immunoh...

While first and foremost considered a respiratory infection, COVID-19 can result in complications affecting multiple organs. Immune responses both protect against the disease as well drive it. Insights into these responses, specifically targets being recognised by immune system, are of vital importance understanding side effects associated pathologies. The body’s adaptive immunity recognises re...
