MS is an inflammatory-mediated demyelinating disease that has been associated with production of interferon (IFN)-γ and interleukin (IL)-17, two cytokines that are produced by Th1 and Th17 cells, respectively 12 . (nature.com)
More recently, the role of Th1 and Th17 CD4 + cells in the pathogenesis of experimental autoimmune encephalomyelitis (EAE), the most commonly used experimental model for human MS, has been challenged, and it has been demonstrated that the transcription factor T-bet (also known as Tbx21 ) is critical for controlling Th1/Th17-mediated autoimmunity 12 .

Dr. Muir is also a senior level expert in flow cytometry and fluorescence activated cell sorting (FACS) with 15 years' experience. (drexel.edu)

They point out that if pre-existing CD4 + T RM cell immunity was so extreme as to preclude significant viral replication, seroconversion (that is, a de novo antibody response to SARS- CoV-2) would not occur. (wattsupwiththat.com)
Changes in these cells were similar to some known to occur in obesity, insulin resistance and type 2 diabetes, she adds. (sciencedaily.com)
In 3D cell culture, contamination can occur in various components, such as the bio-ink or the extracellular matrix . (corning.com)

Researchers now have demonstrated that umbilical cells from children of obese or overweight mothers show impaired expression of key genes regulating cell energy and metabolism, compared to similar cells from babies of non-obese mothers. (sciencedaily.com)
In this genomic age, one possible answer is that a cell can be defined by a profile of all of the genes it is expressing. (genengnews.com)
Microarray technology and next-generation sequencing methods have enabled us to see all of the genes expressed by a given cell type at any particular time, or under a particular circumstance. (genengnews.com)

SARS-CoV-2 T cells (either CD4 + , CD8 + or both) were detectable in 70 patients. (nature.com)
SARS-CoV-2 IFN-γ CD4 + T-cell responses were documented more frequently than their CD8 + counterparts (62 vs. 56 patients) and were of greater magnitude overall. (nature.com)
New research in clustered regularly interspaced short palindromic repeats (CRISPR) technology suggests that base-edited T cells could be useful in patients with relapsed leukemia and could help anticipate the risks of immunotherapy -related complications. (ajmc.com)
We then outline preclinical approaches that employ CAR-NK cells for GB immunotherapy, and give an overview on the ongoing clinical development of ErbB2 (HER2)-specific CAR-NK cells currently applied in a phase I clinical trial in glioblastoma patients. (frontiersin.org)
Patients with severe combined immunodeficiency (SCID) may present with residual circulating T cells. (hindawi.com)
MHC-II deficient patients had slightly reduced T-cell function, normal TRECs, TCR repertoires, and normal Tregs enumeration. (hindawi.com)
In contrast, patients with self-reactive cells have significant autoimmune features in addition to their clinical and molecular immunodeficient state. (hindawi.com)

The use of base editing to generate universal, off-the-shelf CAR T cells is a promising approach for relapsed leukemia, with potential implications for the future of gene therapy. (ajmc.com)
In the phase 1 study, investigators used base editing to generate universal, off-the-shelf CAR T cells. (ajmc.com)
Using the SURVEYOR nuclease assay 13 , we assessed the ability of each Cas9-sgRNA complex to generate indels in human embryonic kidney (HEK) 293FT cells through the induction of DNA doublestranded breaks (DSBs) and subsequent nonhomologous end joining (NHEJ) DNA damage repair (Online Methods).

"We identified a molecular pathway in muscle stem cells that regulates the process of muscle formation very strongly and efficiently," she recalled. (foodnavigator.com)
Molecular chimerism analysis also confirmed the presence of BE-CAR7 cells, which the study said accounted for most of circulating mono-nuclear cells during the 28 days after infusion. (ajmc.com)

Mild to moderately abnormal cell when viewed under the microscope, not malignant. (ucsfhealth.org)

Most recently, data for the efficacy of the JCAR17 platform for relapsed/refractory diffuse large B-cell lymphoma (DLBCL), the most common lymphoma in the United States, were presented by Dr. Jeremy Abramson and his colleagues at the 2017 International Conference on Malignant Lymphoma.

An interesting new paper by Marc Lipsitch and co-authors, "Cross-reactive memory T cells and herd immunity to SARS-CoV-2", has recently been published. (wattsupwiththat.com)
They argue that key potential impacts of cross- reactive T cell memory are already incorporated into epidemiological models based on data of transmission dynamics, particularly with regard to their implications for herd immunity. (wattsupwiththat.com)
The first point to make is that cross-reactive T cells were never thought to be the main cause of the herd immunity threshold (HIT) [2] being lower for COVID-19 than the oft-quoted {1 - 1/R0} level, which generally applies for vaccination. (wattsupwiththat.com)
Lipsitch and co-authors note that recent reports have shown that SARS- CoV-2 cross-reactive memory T cells, very largely CD4 + T-cells arising from previous exposure to circulating common cold coronaviruses, are detectable in ~28-50% of individuals not exposed to SARS- CoV-2. (wattsupwiththat.com)
The authors go on to propose four immunological scenarios for the impact of cross-reactive CD4+ memory T cells on COVID-19 severity and viral transmission. (wattsupwiththat.com)
The first three scenarios, along with the case where no cross-reactive T cells exist, are represented in Fig.1 of the paper, reproduced below. (wattsupwiththat.com)

These findings identify emperipolesis as a new cell-in-cell interaction that enables neutrophils and potentially other cells passing through the megakaryocyte cytoplasm to modulate the production and membrane content of platelets. (elifesciences.org)

Our preliminary experience with CARTs has been primarily against a variety of relapsed, refractory B-cell malignancies including ALL, CLL, and NHL. (medpagetoday.com)
