Phosphopeptide Neoantigens as Emerging Targets in Cancer Immunotherapy
Protein post-translational modifications play a vital role in various cellular events essential for maintaining cellular physiology and homeostasis. In cancer cells, aberrant post-translational modifications such as glycosylation, acetylation, and phosphorylation on proteins can result in the generation of antigenic peptide variants presented in complex with MHC molecules. These modified peptides add to the class of tumor-specific antigens and offer promising avenues for targeted anti- cancer therapies. In this review, we focus on the role of phosphorylated peptides (p-peptides) in cancer immunity.
Toward Precision Medicine for Patients with Multiple Myeloma
Multiple myeloma (MM), the second most common hematologic malignancy, is a plasma cell neoplasm that arises from a precursor, monoclonal gammopathy of undetermined significance (MGUS), which may or may not be previously diagnosed. Smoldering multiple myeloma (SMM), another precursor of MM, lacks myeloma-defining events and end-organ damage that are diagnostic of MM in the appropriate clinical settings. Newly diagnosed MM (NDMM) is highly heterogeneous genetically and clinically with very variable survival outcomes ranging from a few months to over a decade.

Azot is Not Essential for Loser Cell Elimination in a Time-dependent Manner
Cell competition is a conserved phenomenon spanning from arthropods to humans. It involves the elimination of viable yet suboptimal "loser" cells when juxtaposed with their fitter "winner" counterparts. This process has received increased attention for its implications in cancer initiation and progression, neurodegeneration, and ageing. This study investigates the presence of the loser fitness fingerprint Flower LoseB (Fwe LB) and the fitness checkpoint Azot in the optic lobes over a period of 28 days. Notably, the absence of Azot is conventionally linked to the accumulation of loser cells over time.
Elevated Interleukin-6 (IL-6) Levels with Ig (G & M) Antibodies in the Recovery Phase of Patients with COVID-19: Indication of Cytokine Storm and Re-infection
The innate immune response to coronavirus disease (COVID-19) by inflammatory cytokines, such as interleukin 6 (IL-6), has been described as an early response, followed by an adaptive immune response with the production of antibodies. IL-6 is produced in response to viral infections and is crucial for the activation of T cells and the differentiation of B cells, which produce antibodies. Immunoglobulin M (IgM) and immunoglobulin G (IgG) antibodies are produced during the initial acute period of infection and the recovery period from the period of onset of symptoms.
One-to-one Benefit Provided by Antioxidants to Cultured Skin Fibroblasts from Friedreich Ataxia Patients
As to better understand and characterize the dramatic differences in antioxidant response of human cells harboring mutations in the frataxin gene responsible for Friedreich's ataxia (FRDA), we studied primary cultures of skin fibroblasts derived from five FRDA patients with different major frataxin gene expansion sizes. Since oxidative stress has been previously established to play a critical role in FRDA, among the many enzymes that may modulate oxidative stress sensitivity, we selected some that have previously been shown to be critical in oxidative stress.

Antibiotics, Efflux, and pH
Bacterial metabolism affects the effectiveness of antibiotics. Bacterial metabolism is linked to the ability of an antibiotic to be bactericidal or bacteriostatic because a bacterium can metabolize carbohydrates that affect its pH and its ability to use the proton motive force (PMF). When the pH is low, there is more availability of protons that can help to power the proton motive force needed for the efflux of antibiotics.
Negative Feedback Expansion of Tregs Caused by Endogenous IL-2 Limits the Activity of IL-2-based Therapies
Stimulating effector T-cells (Teffs) without inducing regulatory T-cells (Tregs) has been the primary goal of IL-2-based therapies for cancer. Recently, modified IL-2 designed for differential T-cell expansion for the treatment of cancer has failed in the clinic. We propose that treatments based on exogenous administrations of modified IL-2 are inherently undermined by a negative feedback loop, caused by IL-2 secreted endogenously from activated effector T-cells.

The Dual Role of Macrophages during Hepatitis B Infection
Hepatitis B virus (HBV) chronically infects more than 250 million individuals worldwide and is responsible for more than 800,000 deaths per year by promoting end-stage liver diseases, among which decompensated cirrhosis and hepatocellular carcinoma (HCC) (WHO, July 2020) are prominent. Studies performed in chimpanzees or in animalversion of HBV (woodchuck HBV: WHBV) highlighted the lack of immune responses against the virus upon primary infection. Thus, HBV has been described as a “stealth” virus (i.e. a virus that does not modify/induce immune response in the cell). However, a growing number of studies describe that HBV is able to rapidly and efficiently counteract the innate immune response in a large variety of cells (hepatocytes, macrophages, Natural Killer cell…). Hereby, we focus on the role of macrophages (Mφ) during HBV infection.

pMB FLASH - Status and Perspectives of Combining Proton Minibeam with FLASH Radiotherapy
Proton minibeam radiotherapy (pMBRT) is an external beam radiotherapy method with reduced side effects by taking advantage of spatial fractionation in the normal tissue. Due to scattering, the delivered small beams widen in the tissue ensuring a homogeneous dose distribution in the tumor. In this review, the physical and biological principles regarding dose distribution and healing effects are explained. In the last decade, several preclinical studies have been conducted addressing normal tissue sparing and tumor control in-vitro and in-vivo, using human skin tissue and mouse or rat models. The major results acquired in these studies are summarized. A further newly emerging therapy method is FLASH radiotherapy, i.e. the treatment using ultra-high dose rates. The possibility of combining these methods in proton minibeam FLASH therapy (pMB FLASH) is worked out. Additionally, technical feasibility and limitations will be discussed by looking at simulations as well as preclinical studies and also pointing out new ways of delivering the desired tumor dose, such as interlacing. We will also highlight the opportunities that emerge regarding high dose radiation, hypofractionation and the combination with immunotherapy.
