Inheritance of Acquired Characteristics Revisited

Acquired immunity to malaria.

Naturally acquired immunity to falciparum malaria protects millions of people routinely exposed to Plasmodium falciparum infection from severe disease and death. There is no clear concept about how this protection works. There is no general agreement about the rate of onset of acquired immunity or what constitutes the key determinants of protection; much less is there a consensus regarding the ...

Innate and acquired immunity

• The cells of the immune system are divided into lymphoid and myeloid lineages. The former include T lymphocytes and their subsets identified by CD markers, B lymphocytes and natural killer (NK) cells. The myeloid lineage includes the neutrophils, eosinophils and basophils as well as the monocyte/ macrophage series and platelets. • Innate immunity depends on physical, physiological and chemica...

The Clonal Selection Theory of Acquired Immunity

Drawing upon our knowledge of microbial genetics, Burnet has proposed a theory of antibody formation which offers an explanation for certain poorly understood immunologic phenomena (for example, the persistence of antibody for long periods in the absence of contact with the antigen, and the failure to form antibodies to self-antigens under normal conditions). According to Burnet's hypothesis, a...
