Changing patterns of aspergillosis infections.

Aspergillus may cause a wide range of clinical illnesses. In large part, manifestations depend on the status of underlying local and systemic host immunologic responses. Therefore, it is critical to specifically define the different types of aspergillosis.

Radioresistance of culture-induced augmented natural killer-like activity.

Human NK activity is radiosensitive under the control of X-linked genes. We have evaluated the expression of these genes in other forms of cellular cytotoxicity. The NK radioresistant and radiosensitive phenotype is expressed in ADCC.
