Farmer's lung: The so-called farmer's lung is
a disease caused by a hypersensitivity. The cause is a reaction of IgG
antibodies to large quantities of inhaled antigens in the alveolar walls
of the lungs. It leads to an inflammation of the alveolar walls and
impairs breathing.
FK 506 is a substance which deactivates
T cells. FK 506 and Cyclosporin A are the most commonly used immunosuppressives
which are administered for organ transplants. The rejection reaction
can be largely suppressed by their use.
Foetal erythroblastosis: Foetal erythroblastosis is a serious
form of Rhesus haemolysis in which maternal anti-Rh antibodies are transferred
to the foetus via the placenta, react to paternal antigens on the foetal
erythrocytes and trigger a haemolytic anaemia. This is so serious that
the peripheral blood of the foetus contains almost all immature erythroblasts.
Fungi, such as the one-cell eukaryotic yeasts or the moulds,
can cause a number of types of illnesses. The immune responses to fungi
are complex and made up of humoral and cellular reactions.
