Patients with Multiple Sclerosis Show Robust T-Cell Responses to mRNA COVID-19 Vaccines

New research shows that Multiple Sclerosis (MS) patients undergoing anti-CD20 (aCD20) treatment – which depletes the B cells that contribute to the MS attacks – are able to mount robust T-cell responses to the mRNA COVID-19 vaccines, despite having a muted antibody response to the vaccines.

Low on Antibodies, Blood Cancer Patients Can Fight off COVID-19 with T Cells

Antibodies aren’t the only immune cells needed to fight off COVID-19 — T cells are equally important and can step up to do the job when antibodies are depleted, suggests a new Penn Medicine study of blood cancer patients with COVID-19 published in Nature Medicine.

New immunotherapy target discovered for malignant brain tumors

Scientists say they have discovered a potential new target for immunotherapy of malignant brain tumors, which so far have resisted the ground-breaking cancer treatment based on harnessing the body’s immune system. The discovery, reported in the journal CELL, emerged from laboratory experiments and has no immediate implications for treating patients.

Key Pathway for Activated T-cells Might Be Targeted to Fight GVHD

The study demonstrates that T cell activation increases intracellular trafficking via the endoplasmic-reticulum-to-Golgi pathway, and that a protein known as SEC23B — a subunit of the COPII complex — regulates T cells’ production of these important secretory proteins after activation. The work points toward a new potential therapeutic target for decreasing the severity of graft-versus-host-disease (GVHD), a potentially fatal complication of bone marrow transplantation.

Deep Look at Immune Cells in Patients’ Tumors Reveals Insights on Timing for Treatment Combinations

It’s clear that radiation therapy, or radiotherapy, an approach used to treat cancer since the early 20th century, can be an effective companion to newer, immune-stimulating approaches known as immunotherapy. Research from a team from Roswell Park Comprehensive Cancer Center explains how radiation helps boost the immune system’s ability to fight cancer in combination with immune checkpoint inhibitors — and provides new evidence that the timing of these therapies can make a big difference in how effectively they work together.
