Toxocara canis-originated recombinant C-type lectin improves the disability scores of experimental autoimmune encephalomyelitis in murine in vivo models.

Background: The recombinant C-type lectin protein (r-CTL) derived from Toxocara canis larvae is thought to play a role in promoting regulatory T cell-dominant immune responses in toxocariasis. This study aimed to highlight the therapeutic potential of the r-CTL protein in improving the disability scores of EAE by enhancing the Foxp3-CD25 T cells population.

Methods: The r-CTL was expressed in prokaryotic systems and purified using Ni-NTA spin columns.

Recombinant C-type lectin protein of Toxocara canis increases the population of spleen Foxp3+ regulatory T cells in BALB/c mice.

Toxocara canis (T. canis) is a common parasitic nematode in dogs and cats. Parasitic worms can cause chronic and long-term infections in their host, due to their ability to neutralize the host's defense mechanisms.

Collagen II-primed Foxp3 Transduced T Cells Ameliorate Collagen-induced Arthritis in Rats: The Effect of Antigenic Priming on T Regulatory Cell Function.

Regulatory T cells (Tregs) play a major role in the prevention of autoimmune diseases. Transfer of Foxp3 gene into conventional T cells converts their phenotype to regulatory T cells. Therefore, the question arises as to whether adoptively transferred in vitro differentiated Treg cells specific for a locally expressed antigen might have better inhibitory effects on the progression of the disease as compared with antigen-nonspecific T reg cells.

Neutrophil function (innate immunity) during Ramadan.

Background: Fasting during the month of Ramadan is one of the essential religious practices of Muslims. The aim of this study was to evaluate opsonisation, phagocytosis, and nitroblue tetrazolium (NBT) reduction by white blood cells in normal, healthy, male subjects under non-fasting (before Ramadan) and fasting (after Ramadan) conditions.

Methods: In this study, 13 Muslim men, aged 28-54 years, whose health was confirmed by health application forms, gave blood samples one week before the beginning of the holy month of Ramadan and during the last week of Ramadan.

Alterations in the serum levels of chemokines 20 years after sulfur mustard exposure: Sardasht-Iran Cohort Study.

The serum levels of four important and well characterized inflammatory chemokines including MCP-1/CCL2, RANTES/CCL5, IL-8/CXCL8 and Fractalkine/CX3CL1 were evaluated in sulfur mustard (SM) exposed Iranian population 20 years after exposure. In this historical cohort study 372 SM exposed participants from Sardasht, and 128 unexposed participants as controls were studied. The serum concentrations of chemokines were measured by a sandwich ELISA technique.
