The time course of cancer regression is usually within months of lymph node biopsy, similar to the course of spontaneous regression in our patient which happened within a year after fine-needle biopsy, making immunological mechanism in our case plausible.
An immunological mechanism was also proposed when lipopolysaccharide injection of Salmonella typhi resulted to pancreatic edema in animals.
Furthermore, recent studies have attempted to elucidate the immunological mechanism of influenza virus complicated by bacterial superinfection.
This cross-sectional histomorphometric study was conducted to establish the potential role of endometrial [CD56.sup.+] NK cells as an immunological mechanism in unexplained infertility.

A mild decrease in [CD.sub.4] cells was proposed as an immunological mechanism for this unique manifestation of HSV coinfection with HIES.

The scientists, led by Dr Dale Umetsu, from Harvard Medical School in Boston, US, wrote: "Our results suggest that infection with certain micro-organisms can prevent the subsequent development of asthma and allergy by expanding the relative proportion of a specific subset of NKT cells, thus providing an immunological mechanism for the hygiene hypothesis."
The clinical reaction of leprosy in HIV co-infected patients, whether it occurs after HAART, or ALT or, for that matter, in the absence of either, is clinically indistinguishable, thus suggesting some common underlying immunological mechanism. The possible explanations underlying leprosy IRIS could be that HAART may provide the immunological 'trigger' to the antigens present leading to the development of sub polar tuberculoid form of disease.
