Responses of lymphocytes from human colostrum or milk to influenza antigens

Abstract

Paired samples of peripheral blood and colostrum or milk were obtained from women 1 to 6 days after delivery. After Ficoll-Hypaque centrifugation, peripheral blood lymphocytes (PBL) and colostrum or milk lymphocytes (COL) were examined for surface membrane characteristics and in vitro proliferative reactivity. As determined by sheep red blood cell rosetting and by immunoglobulin-coated beads, PBL showed an average of 54% T and 12% B lymphocytes, whereas COL showed 33% T and 22% B rosettes, respectively. Paired samples of PBL and COL were used for lymphocyte transformation with three distinct strains of influenza virus: A/USSR, A/Victoria, and B/Hong Kong. Of COL from nine subjects tested against all three strains of influenza virus, five samples (56%) gave positive responses to at least one. These studies indicate that COL contain cells responsive in vitro to several influenza antigens. Such sensitized cells may provide a mechanism for the transfer of antigen responsiveness and protection from the mother to the neonate.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.
