We’re delighted to hear that our favourite cell type (Regulatory T cells!) have been recognised in the Nobel Prize this year! Huge congratulations to Mary, Fred, and Shimon for their pivotal work in the field & here’s to many exciting Treg advances to come!🥳👏🎉

A small primer on the #NobelPrize awarded to Mary E. Brunkow, Fred Ramsdell and Shimon Sakaguchi today. This prize was for combining two separate fields of immunology research - genetic research on IPEX and immunology research of regulatory T cells (#Tregs), with enormous impact on biology/medicine

Definitely more important than MHRA suicide risks. Five days ciprofloxacin up to year-long resistance in the gut microbiome (10 % got same gyrA mutation with no fitness cost). Probably had impact on tonic mucosal immune responses too.

Tuberculosis in NYC: Why have cases been on the rise? In the 1990s, NYC faced a surge of tuberculosis. The city bolstered its TB control program and brought those cases down. But in recent years, they’ve started to tick up again. Here’s what to know abou...

From 2022 to 2023 the city of new york reported a 28% increase in cases of tuberculosis. This article examines the reasons. The biggest one is the continued loss of public health funding.

Proud of my group and collaborators for this work published today in Nature Medicine. We find Cytomegalovirus, which has a profound impact on T cell immunity, is associated with distinct clinical outcomes in patients receiving checkpoint immunotherapy for melanoma.

Adjuvant mechanisms of action at the injection site. Antigen depots control the rate of antigen release at the injection site, where local inflammation and slow release of both antigen and adjuvant components influence cytokine and chemokine release and subsequent immune cell infiltration from the circulation. Adjuvants can also improve antigen capture by DCs and lymphatic drainage by nanoscale-particulate antigens and increase lymphatic flow leading to enhancement of the immune response.CREDIT: A FISHER/SCIENCE IMMUNOLOGY

Adjuvant effects in the draining lymph node. Adjuvants can have many effects at the draining lymph nodes, including (1) increasing lymph flow; (2) inducing deletion of sinus-lining macrophages, promoting antigen entry into the lymph node parenchyma; (3) promoting antigen capture on follicular DCs in GCs, e.g., via slow antigen release that promotes early immune complex formation or complement activation; (4) inducing the production of inflammatory cytokines and chemokines; (5) promoting influx of innate and adaptive immune cells from circulation; (6) activating innate immune cells, including APCs that up-regulate costimulatory receptors and prepare to present antigen to lymphocytes; and (7) promoting antigen processing and presentation, including cross-presentation of antigen to CD8 T cells by DCs.CREDIT: A FISHER/SCIENCE IMMUNOLOGY

Chemical structures of molecular adjuvants. Adjuvants in use alone or in combination, including the TLR4 agonist monophosphoryl lipid A (MPLA), STING agonist cyclic guanosine 5′-monophosphate (GMP)–adenosine 5′-monophosphate (AMP) (c-GAMP), QS-21 saponin, and TLR7/8 agonist imidazoquinoline 3M-052.CREDIT: A FISHER/SCIENCE IMMUNOLOGY

Adjuvant classes and structures. (A) Depot-forming adjuvants retain antigen for slow release and/or promote immune cell recruitment to the injection site to enable antigen capture and trafficking to draining lymph nodes. Examples of depot-forming adjuvants include aluminum salts, hydrogels, and cationic liposomes. (B) Oil-in-water or water-in-oil emulsions promote innate immune activation through inflammasome activation and induction of cell stress at the injection site and/or draining lymph nodes. (C) Saponins derived from Q. saponaria bark activate inflammasomes, trigger cytokine production, and increase lymph flow. (D) DAMPs or pathogen-associated molecular patterns (PAMPs) are ligands that activate specific pattern recognition receptors like TLRs or other sensors. (E) Combination adjuvant formulations.

Impressive.

Key take homes for me.
1) Time to result still long - addressable but a barrier currently.
2) 10% contamination.
3) Despite using cutting edge tests a "causative" organism found in only 15%.
