Differential Expression of O-Glycans in CD4(+) T Lymphocytes from Patients with Systemic Lupus Erythematosus.

T cells from patients with systemic lupus erythematosus (SLE) show a decreased activation threshold and increased apoptosis. These processes seem to be regulated by glycosylated molecules on the T cell surface. Here, we determined through flow cytometry the expression of mucin-type O-glycans on T helper cells in peripheral blood mononuclear cells (PBMC) from 23 SLE patients and its relation with disease activity.

Transfer factor and allergy.

Although various mechanisms involving antibodies and various cell types participate, a Thl and Th2 cells imbalance seems to play a central role for allergy development. Other lymphocyte subpopulations, such as Th17, CD4 FOXP3, and Th9 positive regulatory T lymphocytes may also be involved in the allergic response. Regulatory processes are an appealing target for therapeutic approaches aiming to solve allergic reactions by restoring the delicate balance within the immune system.

Indications, usage, and dosage of the transfer factor.

The transfer factor (TF) was described in 1955 by S. Lawrence. In 1992 Kirkpatrick characterized the specific TF at molecular level.
