Top 7 in immunology
A snapshot of the most highly ranked articles in immunology and related areas, from Faculty of 1000
linkurl:1. Tracking B-cell movement;http://f1000.com/6837956?key=g8f7jn6yc79cycx
By applying GFP technology in a new way, authors tracked B-cell maturation in the lymph nodes as the cells move from an area of rapid proliferation to an area where B cells that produce the best antibodies are selected, and back again, and found an essential role of T helper cells in this transition.

The first naturally occurring virus infection in C. elegans provides researchers with a genetically tractable model for studying virus-host interactions, innate immunity and the evolution of small RNA viral defenses.

linkurl:3. Immune battle by suicide;http://f1000.com/6275956?key=3w8cs548zw610j1

Macrophages infected with Salmonella have an unusual way of killing the pathogen -- they initiate cell suicide, releasing the bacteria, along with inflammatory cytokines, into the extracellular matrix where neutrophils and other immune cells attack them.
E.A.Miao et al., "Caspase-1-induced pyroptosis is an innate immune effector mechanism against intracellular bacteria," linkurl:__Nat Immunol,__;http://www.ncbi.nlm.nih.gov/sites/entrez/21057511?dopt=Abstract&holding=f1000%2Cf1000m 11:1136-42, 2010.

linkurl:4.Identifying the unknown;http://f1000.com/7792962?key=dx0nw38p878tf3l
Researchers present a novel method for identifying antibody biomarkers for diseases without known antigens. The technique, which involves searching for antibodies that bind to various synthetic molecules, may prove useful for identifying diagnostic markers in a wide variety of diseases.

Reddy, et al., "Identification of candidate IgG biomarkers for Alzheimer's disease via combinatorial library screening," linkurl:__Cell,__;http://www.ncbi.nlm.nih.gov/sites/entrez/21215375?dopt=Abstract&holding=f1000%2Cf1000m 144:132-42, 2011.

linkurl:5. Mitochondria cause inflammation;http://f1000.com/2411956?key=twklz4nb2vf24wm
Innate immune receptors that initiate inflammation in response to bacterial fragments also appear to respond to mitochondrial DNA, which is released into the blood during tissue injury -- an observation possibly linked to the organelle's bacterial origins -- could explain the whole-body inflammation that occurs when mitochondria-rich organs like the heart are damaged.
Q. Zhang et al., "Circulating mitochondrial DAMPs cause inflammatory responses to injury," linkurl:__Nature,__;http://www.ncbi.nlm.nih.gov/sites/entrez/20203610?dopt=Abstract&holding=f1000%2Cf1000m 464:104-7, 2010.

linkurl:6. IL-7 jump starts inflammation;http://f1000.com/8506956?key=y4cc31bm6t7t4c5
While the body often stops responding to chronic viral infections, interleukin 7 (IL-7) can rejuvenate the immune system by activating the cytokine signaling that is repressed by the a genetic switch SOCS3, and by increasing the production of IL-22, a cytokine that protects organs like the liver and gut from damage, suggesting IL-7 may be useful in anti-viral therapies for chronic infections like HIV.

Pellegrini et al., "IL-7 Engages Multiple Mechanisms to Overcome Chronic Viral Infection and Limit Organ Pathology," linkurl:__Cell,__;http://www.ncbi.nlm.nih.gov/sites/entrez/21295337?dopt=Abstract&holding=f1000%2Cf1000m 144:601-13, 2011.

linkurl:7. Basophils not so necessary;http://f1000.com/5162972?key=22d99m8dpk8g055
Despite the importance of basophils, a type of white blood cell, in protecting the body against parasitic worms and chronic allergic inflammation, researchers have found that T helper cells can respond effectively to allergens and worms without activation by basophils.
C. Ohnmacht et al., "Basophils orchestrate chronic allergic dermatitis and protective immunity against helminths," linkurl:__ Immunity,__;http://www.ncbi.nlm.nih.gov/sites/entrez/20817571?dopt=Abstract&holding=f1000%2Cf1000m 33(3):364-74, 2010.
