Herein is an overview of our observations on the inhibition of the induction of splenic CD4 and CD8+ regulatory T cells, thymic and hepatic regulatory T cells by the ablation of the sympathetic nervous system by the neurotoxin 6-hydroxydopamine (6-OHDA). We suggest that the sympathetic influence on the activation and maintenance of different regulatory T cells is a major neuronal influence of the immune system that could be a major factor in chronic stress.

LinkedIn has announced it is launching a new Linkedin Contacts that aims to create a “personal assistant” for users. You might be thinking you already have a Contacts section in your LinkedIn account – and you’d be right. However, this goes well beyond what LinkedIn offers today under the “Contacts” tab. The new LinkedIn Contacts will reside within LinkedIn and also as a standalone app for iPhone. What’s new about it? With the new LinkedIn Contacts you will be able to see information not only about your LinkedIn connections, but also everybody in your address book, calendars and emails. You can have all your professional contacts in one place, instead of scattered around among LinkedIn, email, and other places. On the official LinkedIn blog, Engineer and Product Specialist Sachin Rekhi writes: “LinkedIn Contacts brings together all your address books, emails, and calendars, and keeps them up to date in one place. From these sources, we’ll automatically pull in the details of your past conversations and meetings, and bring these details directly onto your contact’s profile.” (...) - By Joshua Sophy, Small Business Trends, April 29, 2013 Via Julien Hering, PhD

Afferent vagal pathways transmit information to the brain related to peripheral inflammation so as to participate in the activation of adaptive reactions, including fever and sickness behavior. On the other side, efferent vagal pathways inhibit the synthesis and release of pro-inflammatory cytokines by peripheral immune cells. Because activation of afferent vagal pathways by immune stimuli leads to suppression of immune reactions, the term inflammatory reflex was introduced. Delete the scoop?

In this study, Laurence Macia and colleagues from the Garvan Institute of Medical Research, Darlinghurst, Australia, demonstrate that NPY exacerbates allergic airway inflammation (AAI) in mice, via its Y1 receptor. They found that the development of AAI was associated with elevated NPY expression in the lung and that mice lacking Y1 receptor signaling have significantly reduced symptoms of AAI.

Leukocytes are key components of the body’s defense system and the major subsets of leukocytes are granulocytes and lymphocytes. We and others have found that the distribution of these subsets are under the regulation of the autonomic nervous system. Of note, granulocytes express adrenergic receptors and the number and proportion of granulocytes increase by a stimulation of the sympathetic nervous system. Delete the scoop?

Primary and secondary lymphoid organs are innervated by the autonomic nervous system resulting in release of catecholamines, acetylcholine and peptide transmitters (neuropeptide Y-NPY, substance P-SP, calcitonin gene-related peptide-CGRP and vasoactive intestinal peptide-VIP) in the lymphoid microenvironment. Noradrenergic and neuropeptidergic nerve fibers are found adjacent to cells of the immune system in thymus and spleen regulating the immune responsiveness, lymphocyte cellular functions, collective cellular interactions as well as the overall host immunological response.

To investigate the role of neuroendocrine activation in cancer progression, in this study, Erica K. Sloan and colleagues used in vivo bioluminescence imaging to track the development of metastasis in an orthotopic mouse model of breast cancer. The authors demonstrate that physical restraint, applied as a standardized stressor increased the metastasis of primary breast tumor cells to distant tissues by 38-fold, and stress increased metastasis in clinically relevant tissues, with a 37-fold increase in the lung and a 67% increase in the lymph nodes.

The human nervous system exerts great influence on the homeostasis of the body; this includes regulation of bone marrow processes like hematopoiesis. Tachykinins are small neuropeptides from 10-12 amino acids long synthesized in various nuclei of the central nervous system such as the substania gelatinosa of the dorsal spinal cord and certain nuclei of the limbic lobes as well as in a number of non-neuronal tissues like stromal cells of the BM. Within the bone marrow, the tachykinins have been shown to have critical effects on the microenvironment, including metastasis and dormancy of cancer cells during clinical remission.
