opsonins

The absorption of the pathogenic bacteria, helped by the opsonins, is important but it is only the beginning of a series of phenomena that culminates in the digestion of the microbes within the phagocytes.

This is why, as several doctors have already pointed out, the power of the opsonins is not enough of itself in all cases to ascertain the organism's level of resistance.

Ilya Mechnikov - Nobel Lecture 1967

All research into opsonins and bacteriotropins has been conducted with humours and white corpuscles extracted from the organism and mixed with the microbes in glass test tubes.

Ilya Mechnikov - Nobel Lecture 1967

The opsonins would be important, however, in making the action of the white corpuscles more speedy and more sure.

Ilya Mechnikov - Nobel Lecture 1967

The white corpuscles are taken as constant elements which can only obey the behests of the opsonins.

Ilya Mechnikov - Nobel Lecture 1967

Persuaded of the relative unimportance of the humours as destructive agents to infectious microbes, the followers of the humoral theories have lately fallen back on the opsonins and the bacteriotropins, considered as humoral factors well to the fore in immunity.

Ilya Mechnikov - Nobel Lecture 1967

He even goes so far as to admit the existence of a spontaneous phagocytosis, which evolves without the aid of the opsonins.

Ilya Mechnikov - Nobel Lecture 1967

In the investigations on the opsonins and bacteriotropins, investigations guided by humoral notions, on the whole only the power of the blood fluid to favour phagocytosis is regarded.

Ilya Mechnikov - Nobel Lecture 1967

But, insisting on the preparation of the morbid agents by the opsonins, Wright admits the virtue of the phagocytes in ridding the organism of microbes.

Ilya Mechnikov - Nobel Lecture 1967

If it is true, as a great number of research workers now hold, that the opsonins and the bacteriotropins are mixtures in varying proportions of the complements and the amboceptors, one could easily understand that in the living organism things go on in quite another way than in test-tube experiments.
