ANTIBODY‐PRODUCING CELLS: ANALYSIS AND PURIFICATION BY VELOCITY SEDIMENTATION

Cell Proliferation, 1970
ABSTRACTVelocity sedimentation cell separation is a simple and reproducible method for obtaining highly enriched populations of viable antibody‐producing cells. Using suspensions of spleen cells prepared from mice immunized with sheep erythrocytes, fractions containing up to 2% 19S‐PFC and 25% 7S‐PFC can be obtained.

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

FEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

Correlation between cell aggregation and antibody production in IgE-producing plasma cells

Biochemistry and Biophysics Reports, 2017
Allergic conditions result in the increase of immunoglobulin (Ig)E-producing plasma cells (IgE-PCs); however, it is unclear how IgE production is qualitatively controlled.

ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

FEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes

FEBS Letters, EarlyView.
GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.

The Calcineurin Inhibitor Tacrolimus Specifically Suppresses Human T Follicular Helper Cells

Frontiers in Immunology, 2018
BackgroundT follicular helper (Tfh) cells are key players in the production of antibody-producing B cells via the germinal center reaction. Therapeutic strategies targeting Tfh cells are important where antibody formation is implicated in disease, such ...

The development of methods for obtaining monoclonal antibody-producing cells

Postępy Higieny i Medycyny Doświadczalnej, 2016
Monoclonal antibodies (mAbs) are biomolecules of great scientific and practical significance. In contrast to polyclonal antibodies from immune sera, they are homogeneous and monospecific, since they are produced by hybridoma cells representing a clone arising from a single cell.

Structure‐forward targeting of claudins with synthetic binders

FEBS Letters, EarlyView.
Claudins form the paracellular barriers between epithelial and endothelial tissues at tight junctions and are targets for molecular binders with the goal of modulating barrier permeability. Claudin‐binding molecules are relevant in drug delivery or in altering claudin interactions with disease‐causing proteins.

Effect of Euglena gracilis EOD-1 species-derived paramylon intake on lung mucosal anti-β-glucan IgA antibody production in mice

Journal of Functional Foods
Paramylon (PM) is an insoluble dietary fiber derived from Euglena gracilis. Mechanisms underlying the health-promoting effects of Paramylon ingestion remain unclear. Hence, this study aimed to investigate the effect of PM derived from E.

Nutrient/TOR signaling controls adipose mitochondrial transcription factor A (TFAM) to regulate organismal growth in Drosophila

FEBS Letters, EarlyView.
Animals must match their growth rate to available nutrients. We show that in Drosophila larvae, the nutrient‐sensing TOR kinase controls growth by regulating levels of TFAM, a key regulator of mitochondrial function, in the adipose tissue. When nutrients are abundant, high TOR activity suppresses TFAM, lowering mitochondrial bioenergetic activity and ...
