Since pulmonary nodules are its most common radiological feature, they can clinically and radiologically mimic lung cancer, TB, and other pulmonary mycoses. The sensitivity of cultures and the Cryptococcal (CrAg) antigen with lateral flow device on serum are rarely positive in the absence of disseminated disease. [20]
The hook effect refers to the prozone phenomenon, also known as antibody excess, or the postzone phenomenon, also known as antigen excess. It is an immunologic phenomenon whereby the effectiveness of antibodies to form immune complexes can be impaired when concentrations of an antibody or an antigen are very high.
This is a list of major breast cancer cell lines that are primarily used in breast cancer research. [Notes 1] List of cell lines. Cell line Primary tumor
Tumor antigen is an antigenic substance produced in tumor cells, i.e., it triggers an immune response in the host. Tumor antigens are useful tumor markers in identifying tumor cells with diagnostic tests and are potential candidates for use in cancer therapy. The field of cancer immunology studies such topics.
Cryptococcal antigen from cerebrospinal fluid is thought to be the best test for diagnosis of cryptococcal meningitis in terms of sensitivity, though it might be unreliable in HIV-positive patients. [12] The first genome sequence for a strain of C. neoformans (var. neoformans; now C. deneoformans) was published in 2005. [5]
Staging of breast cancer is one aspect of breast cancer classification that assists in making appropriate treatment choices, when considered along with other classification aspects such as estrogen receptor and progesterone receptor levels in the cancer tissue, the human epidermal growth factor receptor 2 status, menopausal status, and the ...
Cryptococcus is a genus of fungi in the family Cryptococcaceae that includes both yeasts and filamentous species. The filamentous, sexual forms or teleomorphs were formerly classified in the genus Filobasidiella , while Cryptococcus was reserved for the yeasts.
ICAM-1 is a ligand for LFA-1 , a receptor found on leukocytes. [9] When activated, leukocytes bind to endothelial cells via ICAM-1/ LFA-1 and then transmigrate into tissues. [ 10 ] LFA-1 has also been found in a soluble form, [ 11 ] which seems to bind and block ICAM-1.
