TLDR
Neutrophils around the marginal zone (MZ) of the spleen, a B cell area specialized in T cell–independent immunoglobulin responses to circulating antigen, are identified, which indicates that neutrophils generate an innate layer of antimicrobial immunoglOBulin defense by interacting with MZ B cells.Abstract:
Follicular T cells provide help to B cells to elicit antibody responses. Cerutti and colleagues show that neutrophils provide help to marginal-zone B cells that produce T cell–independent antibodies.read more

Neutrophil recruitment and function in health and inflammation
Elzbieta Kolaczkowska,Paul Kubes +1 more
TL;DR: The key features of the life of a neutrophil are discussed, from its release from bone marrow to its death, and the mechanisms that are used by neutrophils to promote protective or pathological immune responses at different sites are explained.
Journal ArticleDOI
The Multifaceted Functions of Neutrophils
TL;DR: Primordial neutrophil functions are discussed, and more recent evidence that interactions between neutrophils and adaptive immune cells establish a feed-forward mechanism that amplifies pathologic inflammation is presented.
Journal ArticleDOI
Neutrophil: A Cell with Many Roles in Inflammation or Several Cell Types?
TL;DR: The concept of neutrophils phenotypic and functional heterogeneity is presented and several neutrophil subpopulations reported to date are described and the role these sub Populations seem to play in homeostasis and disease is discussed.
Journal ArticleDOI
Neutrophils at work
TL;DR: This Review examines in vivo observations of the recruitment of neutrophils from blood to tissues in models of blood-borne infections versus bacterial invasion through epithelial linings, and examines data on novel aspects of the activation of NADPH oxidase and the heterogeneity of phagosomes.
Journal ArticleDOI
Marginal zone B cells: virtues of innate-like antibody-producing lymphocytes
TL;DR: This Review discusses how marginal zone B cells function as innate-like lymphocytes that mount rapid antibody responses to both T cell-dependent and Tcell-independent antigens.

Neutrophil extracellular traps kill bacteria
Volker Brinkmann,Ulrike Reichard,Christian Goosmann,Beatrix Fauler,Yvonne Uhlemann,David S. Weiss,Yvette Weinrauch,Yvette Weinrauch,Arturo Zychlinsky +8 more
TL;DR: It is described that, upon activation, neutrophils release granule proteins and chromatin that together form extracellular fibers that bind Gram-positive and -negative bacteria, which degrade virulence factors and kill bacteria.

Myeloid-derived suppressor cells as regulators of the immune system.
TL;DR: The origin, mechanisms of expansion and suppressive functions of MDSCs, as well as the potential to target these cells for therapeutic benefit are discussed.

Class Switch Recombination and Hypermutation Require Activation-Induced Cytidine Deaminase (AID), a Potential RNA Editing Enzyme
Masamichi Muramatsu,Kazuo Kinoshita,Sidonia Fagarasan,Shuichi Yamada,Yoichi Shinkai,Tasuku Honjo +5 more
TL;DR: Results suggest that AID may be involved in regulation or catalysis of the DNA modification step of both class switching and somatic hypermutation in CH12F3-2 B lymphoma.

Microbial translocation is a cause of systemic immune activation in chronic HIV infection

TL;DR: It is shown that increased lipopolysaccharide is bioactive in vivo and correlates with measures of innate and adaptive immune activation, which establish a mechanism for chronic immune activation in the context of a compromised gastrointestinal mucosal surface and provide new directions for therapeutic interventions that modify the consequences of acute HIV infection.

Circulating mitochondrial DAMPs cause inflammatory responses to injury
Qin Zhang,Mustafa Raoof,Yu Chen,Yuka Sumi,Tolga Sursal,Wolfgang G. Junger,Karim Brohi,Kiyoshi Itagaki,Carl J. Hauser +8 more
TL;DR: It is shown that injury releases mitochondrial DAMPs into the circulation with functionally important immune consequences, including formyl peptides and mitochondrial DNA, which promote PMN Ca2+ flux and phosphorylation of mitogen-activated protein (MAP) kinases, thus leading to PMN migration and degranulation in vitro and in vivo.
