(12) Reactive metabolites which suppress splenic humoral immune responses are thought to be generated within the spleen rather than in distant tissues.
(13) Release of 51Cr was apparently a function of immune thymus-derived lymphocytes (T cells) because it was abrogated by prior incubation of spleen cells with anti-thymus antiserum and complement but was undiminished by passage of spleen cells through nylon-wool columns.

(20) Our results on humoral and cellular components of immunity in dependence of age, according to SENIEUR protocol admission criteria are presented.
Variolation
Definition:
(n.) Inoculation with smallpox.
Example Sentences:

(3) Man's first attempt to immunize susceptibles against smallpox infection was by variolation, a practice which could be traced back several thousand years.
(4) Variolation is an ancient method of protection against naturally acquired smallpox that was officially proscribed in the early 1950s but was renewed in remote areas when smallpox vaccination activities were interrupted during the three-year famine of 1959-1962, following the "great leap forward" program of 1958.
