Comprehensive Tissue Cytometry Analysis of CD3+ T cells in Lungs of COVID-19 Patients
June, 2022
The appearance of a novel highly infectious human coronavirus (SARS-CoV-2) in 2019 resulted in a global pandemic that caused social and economic devastation worldwide. Infection with SARS-CoV-2 has a highly heterogenous presentation but can lead to life-threatening respiratory failure, even in otherwise healthy individuals.

IBEX and StrataQuest image analysis compatibility
May, 2022
One of the challenges of imaging tissue sections is dealing with their diverse composition. The human body contains hundreds of different cell phenotypes, with many more to be discovered. There is a huge need for multiplexing imaging techniques that can recover imaging information on cell-cell interactions with sufficient resolution to identify various unique phenotypes and is compatible with the diversity of cell species.

PD-L1 raises new hope in the treatment of cutaneous leishmaniasis
January, 2022
Cutaneous leishmaniasis (CL) caused by infection with the Leishmania protozoan is endemic in Sri Lanka. The disease is transmitted by the sandfly and causes widespread burden due to the social stigma causing sufferers to be ostracized and forced into financial hardship. Treatments for cutaneous leishmaniasis have limited success and so, once contracted, patients often face a lifetime of misery.

Enhancing CAR-T Cell Therapy for Glioblastoma
October, 2021
Surgery, chemotherapy and radiation have formed the mainstay of cancer therapy for many years. However, in addition to destroying tumor cells, these treatments are detrimental to healthy cells giving rise to side effects, which can be severe. During the last two decades, more targeted therapies that specifically destroy cancer cells have been developed to minimize unwanted side effects.

Redefine the Transcriptional and Epigenetic Signature of Tissue-associated Regulatory T Cells
September, 2021
Recently Delacher and colleagues were able to redefine the transcriptional and epigenetic signature of tissue-associated regulatory T cells (Treg) in mice and humans (Delacher et al. 2021). They could demonstrate, that Treg cells from healthy tissues share distinct expression patterns with tumor-infiltrating Treg cells...

Evaluating the Nature of Immune Responses to Implanted Polypropylene Mesh
July, 2021
Surgical mesh is used in a range of tissue repair procedures to stabilize and strengthen soft tissue defects or to support prolapsed organs and viscera. One of their most common applications is hernia repair. The mesh serves to mechanically strengthen the weakened area while simultaneously providing a scaffold to support the growth of new tissue...

Understanding HCC Development and Progression
May, 2021
Liver cancer is the fourth leading cause of cancer-related death worldwide, of which hepatocellular carcinoma (HCC) is the most common primary cancer accounting for 75-85% of cases. HCC can be classified into several histological subtypes, reflecting the heterogeneity of the disease. This heterogeneity, including the cancers’ cell plasticity, is known to be, in part, determined by the microenvironment.

Striosomes Causal Changes Task Engagement
Febuary, 2021
Learning through affective responses, in which experiences are regarded as having a positive or negative valence (e.g., pleasure or fear, respectively), requires a judgment of the relative value of options. Several studies have linked a cluster of neurons in the subcortical basal ganglia, known as the striatum, to learning these valence-based responses.

Mediating Palatability Guided Food and Water Consumption with Hindbrain Double Negative Feedback
October, 2020
Animal survival relies on neural mechanisms that trigger behaviors to meet basic bodily needs. Traditionally, motivated behaviors have been categorized into three phases.

COVID-19 Shows a Loss of Bcl6 Expressing T Follicular Helper Cells and Germinal Centers
August, 2020
A groundbreaking publication in the journal Cell suggests that in COVID-19 patients the differentiation of Tfh cells and formation of germinal centers within lymph nodes and spleen is inhibited. Molecules such as Bcl-6 were assessed using the TissueFAXS platform including the analysis applications StrataQuest and TissueQuest.

Imaging of neural contributions to voluntary hand movement
Febuary, 2019
Skilled motor behavior requires the precise exchange of information between the muscles of the body and various levels of the central nervous system (CNS). Motor behavior, limb mechanics and neural control must be precisely coordinated in order to achieve the required movement.
