. B Cells Produce Type 1 IFNs in Response to the TLR9 Agonist CpG-A Conjugated to Cationic Lipids. J Immunol. 2017;199:931-940 pubmed publisher
..These findings fill an important gap in our understanding of the B cell response to CpGs, with implications for the use of CpG-A and CpG-B as immunomodulators. ..

. Intrinsic properties of human germinal center B cells set antigen affinity thresholds. Sci Immunol. 2018;3: pubmed publisher
..The pod-like structures also mediated affinity-dependent antigen internalization by unconventional pathways distinct from those of naïve B cells. Thus, intrinsic properties of human GC B cells set thresholds for affinity selection. ..

. Second signals rescue B cells from activation-induced mitochondrial dysfunction and death. Nat Immunol. 2018;19:871-884 pubmed publisher
..Thus, BCR signaling seems to activate a metabolic program that imposes a limited time frame during which B cells either receive a second signal and survive or are eliminated. ..

..Thus, the cSH2 domain functions not only to inhibit the active site of PLC-Î³2 but also to directly or indirectly stabilize the early BCR signaling complex. ..

. Inhibiting the Mammalian target of rapamycin blocks the development of experimental cerebral malaria. MBio. 2015;6:e00725 pubmed publisher
..Here we report results that open a new avenue for the development of highly selective adjunctive therapies for cerebral malaria by targeting pathways that regulate host and parasite metabolism. ..
Pierce S, Miller L. World Malaria Day 2009: what malaria knows about the immune system that immunologists still do not. J Immunol. 2009;182:5171-7 pubmed publisher
..A close second is the antigenic targets in malaria and how to overcome the enormous polymorphism of these targets. Meeting these challenges represents a call to arms of basic immunologists to advance our knowledge of malaria immunity. ..
