Though multiple relapses and serial shortening of remission is one of the characteristics of follicular lymphoma (FL), standard third- and later-line treatments with clear evidence have not yet been established. Tazemetostat, the first oral enhancer of zester homolog 2 ( inhibitor, showed a favorable clinical outcome and safety profile against relapsed mutant FL in a clinical trial and was applied to this clinical setting. Peripheral blood involvement, known as the leukemic phase, was observed in approximately 10% of patients with FL and reported as a poor prognostic factor.

Article Synopsis
  • Hypertrophic pachymeningitis (HP) is a rare condition that causes inflammation and thickening of the dura mater, the outer layer of the protective covering of the brain and spinal cord.
  • It is commonly associated with other inflammatory diseases, particularly ANCA-associated vasculitis and IgG4 related disease, with very few cases linked to hematologic disorders.
  • The reported case discusses a patient with myelodysplastic syndrome (MDS) who developed HP, suggesting a possible connection between these two conditions.

Corneal fibroblasts maintain homeostasis of the corneal stroma by mediating the synthesis and degradation of extracellular collagen, and these actions are promoted by transforming growth factor-β (TGF-β) and interleukin-1β (IL-1β), respectively. The cornea is densely innervated with sensory nerve fibers that are not only responsible for sensation but also required for physiological processes such as tear secretion and wound healing. Loss or dysfunction of corneal nerves thus impairs corneal epithelial wound healing and can lead to neurotrophic keratopathy.

Article Synopsis
  • Periodontal diseases, such as gingivitis, are common in individuals with intellectual disabilities (ID) and are harder to treat due to difficulties in patient cooperation.
  • A study comparing 16 individuals with ID to 14 healthy controls found significant differences in oral health metrics, such as higher plaque and gingival index scores in the ID group, though the number of decayed, missing, and filled teeth was similar.
  • The oral bacterial diversity in those with ID was lower, with higher levels of certain bacteria (Tannerella spp. and Treponema spp.) and lower levels of Porphyromonas spp. compared to healthy controls, highlighting important microbial differences.

SARS-CoV-2 has gradually acquired amino acid substitutions in its S protein that reduce the potency of neutralizing antibodies, leading to decreased vaccine efficacy. Here, we attempted to obtain mutant viruses by passaging SARS-CoV-2 in the presence of plasma samples from convalescent patients or vaccinees to determine which amino acid substitutions affect the antigenicity of SARS-CoV-2. Several amino acid substitutions in the S2 region, as well as the N-terminal domain (NTD) and receptor-binding domain (RBD), affected the neutralization potency of plasma samples collected from vaccinees, indicating that amino acid substitutions in the S2 region as well as those in the NTD and RBD affect neutralization by vaccine-induced antibodies.

Urokinase-type plasminogen activator (uPA) is a serine protease that plays a central role in the pericellular fibrinolytic system, mediates the degradation of extracellular matrix proteins and activation of growth factors, and contributes to the regulation of various cellular processes including cell migration and adhesion, chemotaxis, and angiogenesis. The corneal epithelium responds rapidly to injury by initiating a wound healing process that involves cell migration, cell proliferation, and tissue remodeling. It is innervated by sensory nerve endings that play an important role in the maintenance of corneal epithelial homeostasis and in the wound healing response.

Defining the ontogeny of tumor-associated macrophages (TAM) is important to develop therapeutic targets for mesothelioma. We identified two distinct macrophage populations in mouse peritoneal and pleural cavities, the monocyte-derived, small peritoneal/pleural macrophages (SPM), and the tissue-resident large peritoneal/pleural macrophages (LPM). SPM rapidly increased in tumor microenvironment after tumor challenge and contributed to the vast majority of M2-like TAM.
