Under natural conditions, reactions between viruses and antibodies occur in living host tissues. Because of the importance of such reactions in immunity to virus infections, much attention has been directed toward them. The most nearly natural model which is available for detailed study in the laboratory appears to be the reaction in which the infectivity of a virus is neutralized by homologous...

525 vaccine. The vaccine contained formaldehyde detoxified, aluminium adsorbed diphtheria and tetanus toxins, 25 and 75 flocculation units/ml respectively (SBL, Sweden). The subjects were randomised by using sealed envelopes to receive the vaccine subcutaneously (21 subjects) or intracutaneously (18). The mean age was 29-8 (range 23-43) years, with no difference between the groups. Seven of the...

A brief explanation of cellular and humoral immunity. Although immunity involves every orvm and system of the body, the typical conceptualization of the immune system consists of lymphocytes divided into two major divisions: the humoral mid cellular aspects. Humoral immunity includes primarily B lymphocytes and has to do with antigen/antibody reactions. These are the reactions involved in type ...

Toll-like receptors (TLRs) play an important role in shaping the host immune response to infection and inflammation. Tissue hypoxia is a common microenvironmental feature of infected and inflamed tissues. Furthermore, hypoxia significantly impacts the development of immune and inflammatory responses through the regulation of host innate and adaptive immunity. Here, we will discuss current knowl...
