Summary: Biologically active small molecules can impart modulatory effects, in some cases providing extended long-term memory. In a screen of biologically active small molecules for regulators of tumor necrosis factor (TNF) induction, we identify several

The immune system in chickens , [PDF]
The most sophisticated feature of the immune system expressed in vertebrates is recognition of foreign molecules by distinct types of immunocompetent cells. Birds are the first vertebrates in which a clear dichotomy of the lymphoid system has been established: 1. Thymus-derived (T) lymphocytes, the effector cells in cell-mediated (immunity and 2. Bursa-

Neuroimmune Interactions: From the Brain to the Immune System and Vice Versa.
Because of the compartmentalization of disciplines that shaped the academic landscape of biology and biomedical sciences in the past, physiological systems have long been studied in isolation from each other.

RAG2 and XLF/Cernunnos interplay reveals a novel role for the RAG complex in DNA repair
Antigen receptor diversity relies on careful DNA cleavage and repair. Here the authors identify a functional interplay between RAG2 and XLF during V(D)J recombination, revealing an important role for the RAG complex in repairing induced DNA double-strand

The Role of Molecular Flexibility in Antigen Presentation and T Cell Receptor-Mediated Signaling
Antigen presentation is a cellular process that involves a number of steps, beginning with the production of peptides by proteolysis or aberrant synthesis and the delivery of peptides to cellular compartments where they are loaded on MHC class I (MHC-I ...

Mercury and its toxic effects on fish
Mercury (Hg) and its derivative compounds have been parts of widespread pollutants of the aquatic environment. Since Hg is absorbed by fish and passed up the food chain to other fish-eating species, it does not only affect aquatic ecosystems but also ...
