A ball and stick model of a molecule of Human Interferon. Interferons are proteins important in the working of the immune system and are produced in large numbers in the presence of viruses, bacteria, tumors and parasites.  Interferons are used in drugs to combat cancer, multiple sclerosis, hepatitis B and C and other diseases. Isolated on white.
The study of plant tissues under the microscope in the laboratory.
Rosai–Dorfman disease (RDD) is a rare proliferative histiocytic disorder of unknown etiology. RDD typically presents with generalized lymphadenopathy and polymorphic histiocytic infiltration of the lymph node sinuses; however, occurrences of extranodal soft tissue RDD may rarely occur when masquerading as a soft tissue sarcoma.
