Smad1 Expression in Follicular Lymphoma [PDF]

open access: yesJournal of Pathology and Translational Medicine, 2015
Background: Follicular lymphomas present with various immunohistologic patterns. The immunohistochemical markers used in the diagnosis of follicular lymphoma show variable degrees of sensitivity and specificity, and thus, additional germinal center ...

Spontaneous germinal centers and autoimmunity [PDF]

open access: yesAutoimmunity, 2017
Germinal centers (GCs) are dynamic microenvironments that form in the secondary lymphoid organs and generate somatically mutated high-affinity antibodies necessary to establish an effective humoral immune response. Tight regulation of GC responses is critical for maintaining self-tolerance.

DNA immunisation. New histochemical and morphometric data. [PDF]

open access: yes, 2002
Splenic germinal center reactions were measured during primary response to a plasmidic DNA intramuscular injection. Cardiotoxin-pretreated Balb/c mice were immunized with DNA plasmids encodmg or not the SAG1 protein, a membrane antigen of Toxoplasma ...

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

open access: yesFEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

A MACS protocol for purification of untouched germinal center B cells from unimmunized or germinal center-induced mice

open access: yesSTAR Protocols, 2022
Summary: Highly enriched germinal center (GC) B cell populations are essential for studying humoral immunity. Current MACS protocols that isolate untouched GC B cells require GC induction and typically require further FACS purification with direct ...

Hematopoietic (stem) cells—The elixir of life?

open access: yesFEBS Letters, EarlyView.
The aging of HSCs (hematopoietic stem cells) and the blood system leads to the decline of other organs. Rejuvenating aged HSCs improves the function of the blood system, slowing the aging of the heart, kidney, brain, and liver, and the occurrence of age‐related diseases.

Critical roles of mTOR Complex 1 and 2 for T follicular helper cell differentiation and germinal center responses

open access: yeseLife, 2016
T follicular helper (Tfh) cells play critical roles for germinal center responses and effective humoral immunity. We report here that mTOR in CD4 T cells is essential for Tfh differentiation.

Germinal Centers without T Cells [PDF]

open access: yesThe Journal of Experimental Medicine, 2000
Germinal centers are critical for affinity maturation of antibody (Ab) responses. This process allows the production of high-efficiency neutralizing Ab that protects against virus infection and bacterial exotoxins. In germinal centers, responding B cells selectively mutate the genes that encode their receptors for antigen.

A lesson for cancer research : placental microarray gene analysis in preeclampsia [PDF]

open access: yes, 2012
Tumor progression and pregnancy share many common features, such as immune tolerance and invasion. The invasion of trophoblasts in the placenta into the uterine wall is essential for fetal development, and is thus precisely regulated.

PRMT5 is essential for B cell development and germinal center dynamics

open access: yesNature Communications, 2019
Mechanisms regulating B cell development, activation, education in the germinal center (GC) and differentiation, underpin the humoral immune response. Protein arginine methyltransferase 5 (Prmt5), which catalyzes most symmetric dimethyl arginine protein ...
